It is well-known that many standard algebraic results in the theory of groups, rings, modules, etc., can be proved more generally for suitable categories, in the sense of Eilenberg–Maclane [1945]. This has the usual advantages of abstraction. It singles out those features of a given algebraic structure which are essential to the results in question, and by so doing it extends the validity of these results to other domains. In this Note we shall be concerned with the Krull–Schmidt theorem for modules, which asserts under suitable conditions the existence and essential uniqueness of a direct decomposition into indecomposable factors. It is clear that if such a theorem is to have a meaning in some general category, then such notions as kernel, image and direct sum must be defined in the category, and must possess the usual properties. Such a category, called an exact category, has been considered by Buchsbaum [1955]. Basing ourselves on his paper we then have at our disposal all the necessary notions with the usual properties. Our purpose will be to investigate conditions under which the Krull–Schmidt theorem holds in an exact category. This categorical formulation will then enable us to obtain a Krull–Schmidt theorem for suitable categories of sheaves. This is of special interest in algebraic geometry, and it was this case of the theorem which provided our motivation.

In the theory of differentiable fibre bundles, with a Lie group as structure group, the notion of a connection plays an important role. In this paper we shall consider complex analytic connections in complex analytic fibre bundles. The situation is then radically different from that in the differentiable case. In the differentiable case connections always exist, but may not be integrable; in the complex analytic case connections may not exist at all. In both cases we are led therefore to certain obstructions, an obstruction to the integrability of a connection in the differentiable case, an obstruction to the existence of a connection in the complex analytic case. It is a basic theorem that, if the structure group is compact, the obstruction in the differentiable case (the curvature) generates the characteristic cohomology ring of the bundle (with real coefficients). What we shall show is that, in a large class of important cases, the obstruction in the complex analytic case also generates the characteristic cohomology ring. Using this fact we can then give a purely cohomological definition of the characteristic ring. This has a number of advantages over the differentiable approach: in the first place the definition is a canonical one, not depending on an arbitrary choice of connection; secondly we remain throughout in the complex analytic domain, our characteristic classes being expressed as elements of cohomology groups with coefficients in certain analytic sheaves; finally the procedure can be carried through without change for algebraic fibre bundles.

The Riemann–Roch Theorem for an algebraic variety \( Y \) (see [Hirzebruch 1956]) led to certain divisibility conditions for the Chern classes of \( Y \). It was natural to ask whether these conditions held more generally for any compact almost complex manifold. This question, and various generalizations of it, were raised in [Hirzebruch 1954] and most of these have since been answered in the affirmative in [Borel and Hirzebruch 1958] and [Milnor 1960].

More recently Grothendieck has obtained [Borel and Serre 1958] a more general Riemann–Roch Theorem for a map \( f: Y\to X \) of algebraic varieties. This reduces to the previous Riemann–Roch Theorem on taking \( X \) to be a point. Grothendieck’s Theorem implies many conditions on characteristic classes, and again it is natural to ask if these conditions hold more generally for almost complex or even differentiable manifolds. The purpose of this note is to enunciate certain differentiable analogues of Grothendieck’s Theorem. These “differentiable Riemann–Roch Theorems” yield, as special cases, the divisibility conditions mentioned above and also certain new homotopy invariance properties of Pontrjagin classes. As an application of the latter we get a new proof (and slight improvement) of the result of Kervaire–Milnor [1960] on the stable \( J \)-homomorphism.

Another differentiable Riemann–Roch Theorem, with applications to embeddability problems of differentiable manifolds, will be found in [Atiyah and Hirzebruch 1959].

The proofs of our theorems rely heavily on the Bott periodicity of the classical groups [Bott 1957, 1958, 1959], and are altogether different from the earlier methods of [Borel and Hirzebruch 1958] and [Milnor 1960], which were based on Thom’s cobordism theory and Adams’ spectral sequence.

Nous avons montré dans [Atiyah and Hirzebruch 1959] que le théorème de Riemann–Roch [Borel and Serre 1958] a des analogues différentiables.

La plupart de ces conditions de divisibilité ont été prouvées précédement dans [Borel and Hirzebruch 1958], [Borel and Hirzebruch 1960] et [Milnor 1960]. Dans ce qui suit nous démontrons à l’aide des méthodes de [Atiyah and Hirzebruch 1959] que les classes caractéristiques d’une variété différentiable compacte orientée de dimension \( d \) satisfont aux conditions de divisibilité supplémentaires si la variété peut être différentiablement plongée dans un espace euclidien (ou ce qui est équivalent, une sphère) de dimension \( 2d - q \). Ces conditions de divisibilité «non stables» nous permettent de prouver des théorèmes de non-plongement qui semblent beaucoup plus forts que ceux qui étaient connus avant (3.6). L’outil essentiel est encore le théorème de Bott [Borel and Hirzebruch 1958/59; Bott 1958] qui dit que la \( n \)-ième classe de Chern d’un fibré vectoriel complexe sur la sphère \( S_{2n} \) est divisible par \( (n-1)! \).

The spaces which form the title of this paper were introduced by Thom in [1954] as a tool in his study of differentiable manifolds. In addition certain special Thom complexes have been studied by James [1959] in connexion with Stiefel manifolds (cf. [James 1958a; 1958b]). The purpose of this paper is to prove a number of general results on Thom complexes, and to deduce the main theorems of James [1958b; 1959] as immediate consequences. Our main result (3.3) is a duality theorem (in the Whitehead–Spanier \( S \)-theory) for Thom complexes over differentiable manifolds. Besides its application this is a result of some independent interest, since it provides a satisfactory place for manifolds in \( S \)-theory.

In [1959], [1960] Wall determined the structure of the cobordism ring introduced by Thom in [1953]. Among Wall’s results is a certain exact sequence relating the oriented and unoriented cobordism groups. There is also another exact sequence, due to Rohlin [1953], [1958] and Dold [1959/60] which is closely connected with that of Wall. These exact sequences are established by ad hoc methods. The purpose of this paper is to show that both these sequences are “cohomology-type” exact sequences arising in the well-known way from mappings into a universal space. The appropriate “cohomology” theory is constructed by taking as universal space the Thom complex \( \mathit{MSO}(n) \), for \( n \) large. This gives rise to (oriented) cobordism groups \( \mathit{MSO}^*(X) \) of a space \( X \).

The theorems of Bott [1958, 1959a] on the stable homotopy of the classical groups imply that the sphere \( S^n \) is not parallelizable for \( n \neq 1 \), \( 3, 7 \). This was shown independently by Kervaire [1958] and Milnor [1958; Bott and Milnor 1958]. Another proof can be found in [Borel and Hirzebruch 1959, §26.11]. The work of J. F. Adams (on the non-existence of elements of Hopf invariant one) implies more strongly that \( S^n \) with any (perhaps extraordinary) differentiable structure is not parallelizable if \( n \neq 1 \), \( 3, 7 \). Thus there exist already four proofs for the non-parallelizability of the spheres, the first three mentioned relying on the Bott theory, as given in [Bott 1958, 1959a]. The purpose of this note is to show how the refined form of Bott’s results given in [Bott 1959b] leads to a very simple proof of the non-parallelizability (only for the usual differentiable structures of the spheres). We shall prove in fact the folowing theorem due to Milnor [1958] which implies the non-parallelizability.

There exists a real vector bundle \( \xi \) over the sphere \( S^n \) with \( w_n(\xi) \neq 0 \) only for \( n = 1 \), \( 2,4 \) or 8

In [Borel and Serre 1958] Grothendieck formulated and proved a generalization of the Riemann–Roch theorem which we shall refer to as GRR. This theorem is concerned with a proper morphism \( f:Y\to X \) of algebraic manifolds (any ground field) and reduces to the version (HRR) given in [Hirzebruch 1956] when \( X \) is a point (and the ground field is \( \mathbb{C} \)). It is not known whether GRR or even HRR holds for arbitrary complex manifolds. However the proof of GRR given in [Borel and Serre 1958] breaks up into two separate cases:

\( f \) is an embedding,
\( f \) is a projection \( X\times P_N \to X \), where \( P_N \) is a projective space,

and the main purpose of this paper is to give a proof of GRR in case (i) for arbitrary complex manifolds. This proof is quite different from, and in many ways simpler than, that of [Borel and Serre 1958] and, for the complex algebraic case, it gives a new proof of GRR.

M. F. Atiyah: “Vector bundles and the Künneth formula,” Topology 1 : 3 (1962), pp. 245–248. MR 0150780 article

The purpose of this note is to establish a Künneth formula for the ring \( K^*(X) \) introduced in [Atiyah and Hirzebruch 1960]. We shall prove the following:

Let \( X \), \( Y \) be finite CW-complexes, then we have a natural exact sequence \[ 0 \rightarrow K^*(X)\otimes K^*(Y) \stackrel{\alpha}{\longrightarrow} K^*(X\times Y)\stackrel{\beta}{\longrightarrow} \operatorname{Tor}(K^*(X),K^*(Y)) \rightarrow 0. \]

Here \( \otimes \), \( \operatorname{Tor} \) are applied to abelian groups, and \( \alpha \) is the natural map induced by the product in \( K^* \). Moreover the sequence is \( \mathbb{Z}_2 \)-graded with \( \deg\alpha = 0 \), \( \deg\beta = 1 \), where \( K^p\otimes K^q \) and \( \operatorname{Tor}(K^p,K^q) \) are given degree \( p+q \) (\( p,q \in \mathbb{Z}_2 \)).

Let \( X \) be a complex manifold, \( Y \) a closed irreducible \( k \)-dimensional complex analytic subspace of \( X \). Then \( Y \) defines or “carries” a \( 2k \)-dimensional integral homology class \( y \) of \( X \), although the precise definition of \( y \) presents technical difficu1ties. A finite formal linear combination \( \sum n_iY_i \) with \( n_i \) integers and \( Y_i \) as above is called a complex analytic cycle, and the corresponding homology class \( \sum n_iY_i \) is called a complex analytic homology class. If an integral cohomology class \( u \) corresponds under Poincaré duality to a complex analytic homology class we shall say that \( u \) is a complex analytic cohomology class. The purpose of this paper is to show that a complex analytic cohomology class \( u \) satisfies certain topological conditions, independent of the complex structure of \( X \). These conditions are that certain cohomology operations should vanish on \( u \), for example \( \mathrm{Sq}^3u = 0 \): they are all torsion conditions. We also produce examples to show that these conditions are not vacuous even in the restricted classes of (a) Stein manifolds and (b) projective algebraic manifolds.

In [1960] Gel’fand posed the general problem of investigating the relationship between topological and analytical invariants of elliptic differential operators. In particular he suggested that it should be possible to express the index of an elliptic operator in topological terms. This problem has been taken up by Agranovič [1962a; 1962b], Dynin [1962b; 1961a; 1961b], Seeley [1961; 1963] and Vol’pert [1962] who have solved it in special cases. The purpose of this paper is to give a general formula for the index of an elliptic operator on any compact oriented differentiable manifold. As a special case of this formula we get the Hirzebruch–Riemann–Roch theorem for any compact complex manifold. This was previously known only for projective algebraic manifolds. Some other special cases, of interest in differential topology, are discussed.

The periodicity theorem for the infinite unitary group [Bott 1959] can be interpreted as a statement about complex vector bundles. As such it describes the relation between vector bundles over \( X \) and \( X\times S^2 \), where \( X \) is a compact space and \( S^2 \) is the 2-sphere. This relation is most succinctly expressed by the formula \[ K(X\times S^2) \simeq K(X)\otimes K(S^2), \] where \( K(X) \) is the Grothendieck group of complex vector bundles over \( X \). The general theory of these \( K \)-groups, as developed in [Atiyah and Hirzebruch 1961], has found many applications in topology and related fields. Since the periodicity theorem is the foundation stone of all this theory it seems desirable to have an elementary proof of it, and it is the purpose of this paper to present such a proof.

The \( K \)-theory of complex vector bundles [Atiyah 1965; Atiyah and Hirzebruch 1961] has many variants and refinements. Thus there are:

\( K \)-theory of real vector bundles, denoted by \( \mathit{KO} \),
\( K \)-theory of self-conjugate bundles, denoted by \( \mathit{KC} \) [Anderson 1964] or \( \mathit{KSC} \) [Green 1964],
\( K \)-theory of \( G \)-vector bundles over \( G \)-spaces [Atiyah and Segal 1965], denoted by \( K_G \).

In this paper we introduce a new \( K \)-theory denoted by \( \mathit{KR} \) which is, in a sense, a mixture of these three. Our definition is motivated partly by analogy with real algebraic geometry and partly by the theory of real elliptic operators. In fact, for a thorough treatment of the index problem for real elliptic operators, our \( \mathit{KR} \)-theory is essential. On the other hand, from the purely topological point of view, \( \mathit{KR} \)-theory has a number of advantages and there is a strong case for regarding it as the primary theory and obtaining all the others from it. One of the main purposes of this paper is in fact to show how \( \mathit{KR} \)-theory leads to an elegant proof of the periodicity theorem for \( \mathit{KO} \)-theory, starting essentially from the periodicity theorem for \( K \)-theory as proved in [Atiyah and Bott 1964].

The classical Lefschetz fixed point formula expresses, under suitable circumstances, the number of fixed points of a continuous map \( f:X\to X \) in terms of the transformation induced by \( f \) on the cohomology of \( X \). If \( X \) is not just a topological space but has some further structure, and if this structure is preserved by \( f \), one would expect to be able to refine the Lefschetz formula and to say more about the nature of the fixed points. The purpose of this note is to present such a refinement (Theorem 1) when \( X \) is a compact differentiable manifold endowed with an elliptic differential operator (or more generally an elliptic complex). Taking essentially the classical operators of complex and Riemannian geometry we obtain a number of important special cases (Theorem 2, 3). The first of these was conjectured to us by Shimura and was proved by Eichler for dimension one.

The purpose of this paper is to show how the index theorem of [Atiyah and Singer 1963] can be reformulated as a general “Lefschetz fixed-point theorem” on the lines of [Atiyah and Bott 1967]. In this way we shall obtain the main theorem of [Atiyah and Bott 1967], generalized to deal with arbitrary fixed-point sets, but only for transformations belonging to a compact group.

The content of this paper is essentially topological, and it should be viewed as a paper on the equivariant \( K \)-theory of manifolds. The analysis has all been done in [Atiyah and Singer 1968], and what we do here is simply to express the topological index in terms of fixed-point sets. This is quite independent of the main theorem of [Atiyah and Singer 1968] asserting the equality of the topological and analytical indices.

As in [Atiyah and Singer 1968], we avoid cohomology and use only \( K \)-theory. In paper III of this series, we shall pass over to cohomology obtaining explicit formulas in terms of characteristic classes.

This is the first of a series of papers which will be devoted to a study of the index of elliptic operators on compact manifolds. The main result was announced in [Atiyah and Singer 1963] and, for manifolds with boundary, in [Atiyah 1964]. The long delay between these announcements and the present paper is due to several factors. On the one hand, a fairly detailed exposition has already appeared in [Palais 1965]. On the other hand, our original proof, reproduced with minor modifications in [Palais 1965], had a number of drawbacks. In the first place the use of cobordism, and the computational checking associated with this, were not very enlightening. More seriously, however, the method of proof did not lend itself to certain natural generalizations of the problem where appropriate cobordism groups were not known. The reader who is familiar with the Riemann–Roch theorem will realize that our original proof of the index theorem was modelled closely on Hirzebruch’s proof of the Riemann–Roch theorem. Naturally enough we were led to look for a proof modelled more on that of Grothendieck. While we have not completely succeeded in this aim, we have at least found a proof which is much more natural, does not use cobordism, and lends itself therefore to generalization. In spirit, at least, it has much in common with Grothendieck’s approach.

In [1968a], paper I of this series, the index of an elliptic operator was computed in terms of \( K \)-theory. In this paper, we carry out what is essentially a routine exercise by passing from \( K \)-theory to cohomology. In this way, we end up with the explicit cohomological formula for the index announced in [1963].

In [1968a] we also considered elliptic operators (or complexes) compatible with a compact group \( G \) of transformations. The index in this case is a character of \( G \), and the main theorem of [1968a] gave a construction for this in \( KG \)-theory. In [1968b], paper II of this series, the value of this index-character at an element \( g\in G \) was expressed as the index of a new “virtual operator” on the fixed point set of \( g \). This was referred to as a Lefschetz fixed-point formula. By combining this formula with the cohomological formula for the index, we obtain finally an explicit cohomological formula for the index-character. We shall describe this formula in detail for a number of important operators. In particular we draw attention to the “integrality theorems” obtained in this way for actions of finite groups on manifolds. Most of these do not depend on the analysis in [1968a], but are a consequence of combining the purely topological results of [1968b] and the present paper.

For a compact oriented differentiable manifold \( X \) of dimension \( 4k \) the signature (or index) of \( X \) is defined as the signature of the quadratic form in \( H^{2k}(X;\mathbb{R}) \) given by the cup product. Thus \[\operatorname{Sign}(X) = p - q \] where \( p \) is the number of \( + \) signs in a diagonalization of the given quadratic form and \( q \) is the number of \( - \) signs. If \( \operatorname{dim} X \) is not by divisible by 4 one defines \( \operatorname{Sign}(X) \) to be zero. Then one has the the multiplicative formula \[\operatorname{Sign}(X \times Y) = \operatorname{Sign}(X)\cdot\operatorname{Sign}(Y)\] In [Chern, Hirzebruch and Serre 1957] it was proved that this multiplicative formula continues to hold when \( X \times Y \) is replaced by a fibre bundle with base \( X \) and fibre \( Y \) provided that the fundamental group of \( X \) acts trivially us on the cohomology of \( Y \).

In this paper we exhibit examples which show that this restriction on the action of \( \pi_1(X) \) is necessary, and that the signature is not multiplicative in general fibre-bundles.

It was shown in [Atiyah 1961] that, for any finite group \( G \), the completed character ring \( R(G)^{\wedge} \) was isomorphic to \( K^*(B_G) \) where \( B_G \) denotes a classifying space for \( G \). The corresponding result for compact connected Lie groups was established in [Atiyah and Hirzebruch 1961], and a combination of the methods of [Atiyah and Hirzebruch 1961] and [Atiyah 1961] (together with certain basic properties of \( R(G) \) given in [Segal 1968b]) can be used to derive the theorem for general compact Lie groups. Such a proof however would be extremely lengthy, the worst part being in fact the treatment for finite groups where one climbs up via cyclic and Sylow subgroups.

The purpose of this paper is to give a new and much simpler proof of the theorem about \( K^*(B_G) \) which applies directly to all compact Lie groups \( G \). The main feature of our new proof is that we generalize the whole problem in a rather natural way by working with the equivariant \( K \)-theory developed in [Segal 1968a]. We shall formulate and prove a general theorem about the completion \( K_G^*(X)^{\wedge} \) for any compact \( G \)-space \( X \). The theorem about \( R(G) \) then follows by taking \( X \) to be a point.

In this note I shall show how Hironaka’s theorem [1964] on the resolution of singularities leads very quickly to a new proof of the Hörmander–Lojasiewicz theorem [Hörmander 1958; Lojasiewicz 1959] on the division of distributions and hence to the existence of temperate fundamental solutions for constant-coefficient differential operators. Since most of the difficulties in the general theory of partial differential operators arise from the singularities of the characteristic variety, it is quite natural to expect Hironaka’s theorem to be relevant. In fact, this note is primarily intended to draw the attention of analysts to the power of this theorem. It seems likely that its application in the field of partial differential equations may yield many results besides those described here.

In this paper we give some generalizations of the famous theorem of H. Hopf which states that the number of singularities of a tangent vector field on a compact smooth manifold is equal to the Euler characteristic. Instead of a single vector field we consider \( r \) vector fields \( u_1,\dots,u_r \) and we are interested in their “singularities”, that is, the set \( \Sigma \) of points on the manifold at which they become linearly dependent. In general \( \Sigma \) will have dimension \( r-1 \), it is a cycle and its homology class is the \( (n-r+1) \)-th Stiefel–Whitney class of the manifold. This is the standard primary obstruction theory and it provides one way of generalizing the classical Hopf Theorem. However, this theory says nothing about \( \Sigma \) if \( \dim\Sigma < r-1 \). In this paper following E. Thomas [1967] we shall generalize the Hopf theorem by considering the other extreme case in which \( \Sigma \) is finite, so that \( \dim\Sigma = 0 \).

On a compact complex manifold \( X \) it is an interesting problem to compare the continuous and holomorphic vector bundles. The case of line-bundles is classical and is well understood in the framework of sheaf theory. On the other hand for bundles \( E \) with \( \dim E \geq \dim X \) we are in the stable topological range and one can use \( K \)-theory. Much is known in this direction, for example the topological and holomorphic \( K \)-groups of all complex projective spaces are isomorphic.

This paper deals with what is perhaps the simplest case not covered by the methods indicated above. We shall consider 2-dimensional complex vector bundles over the 3-dimensional complex projective space \( P_3 \). Our aim is to prove

Every continuous 2-dimensional vector bundle over \( P_3 \) admits a holomorphic structure.

In Parts I and II of this paper [1975a; 1975b] we studied the ‘spectral asymmetry’ of certain elliptic self-adjoint operators arising in Riemannian geometry. More precisely, for any elliptic self-adjoint operator \( A \) on a compact manifold we defined \[ \eta_A(s) = \sum_{\lambda\neq 0}\operatorname{sign} \lambda \,|\lambda|^{-s}, \] where \( \lambda \) runs over the eigenvalues of \( A \). For the particular operators of interest in Riemannian geometry we showed that \( \eta_A(s) \) had an analytic continuation to the whole complex \( s \)-plane, with simple poles, and that \( s = 0 \) was not a pole. The real number \( \eta_A(0) \), which is a measure of ‘spectral asymmetry’, was studied in detail particularly in relation to representations of the fundamental group.

In the above paper [Atiyah and Schmid 1977] a key role is played by a result of Borel [1963], concerning discrete subgroups \( \Gamma \) of semisimple Lie groups \( G \). He proves that if \( G \) is linear, one can find a torsion-free \( \Gamma \) with \( \Gamma\backslash G \) compact. Unfortunately we applied this result in [Atiyah and Schmid 1977] even for non-linear \( G \), in which case the existence of such \( \Gamma \) is seriously in doubt, as pointed out to us by P. Deligne and J.-P. Serre. The difficulty is that a torsion-free subgroup of the adjoint group lifts to a cocompact subgroup \( \Gamma \subset G \) which contains the (finite) center \( Z \) of \( G \), and there may be an obstruction to removing this torsion subgroup. As it stands, [Atiyah and Schmid 1977] is correct only for linear \( G \), and we shall now indicate how to extend the proof to cover all \( G \).

Some fifty years ago Einstein’s theory of general relativity provided a great stimulus for different geometry, but after a period of fruitful interaction the interests of geometers and physicists diverged. Within the past few years there has been a resurgence of geometrical ideas in physics, arising partly from the popularity of gauge theories in elementary-particle physics and partly from the work of Hawking and Penrose on black holes. A characteristic feature in both cases has been the significance of global or topological properties, and it is this feature which has particularly attracted mathematicians.

The ideas and problems arising in this way have had a considerable impact on geometry, especially the differential geometry of four dimensions. Through the remarkable twistor theory of Penrose [1977] there is also an intimate connection with complex analytic geometry. In this lecture I shall attempt to survey these mathematical developments with especial emphasis on Penrose’s ideas and their application.

Morse theory is a topological approach to the Calculus of Variations. It aims to relate the critical points of a functional to the topology of the function space on which the functional is defined. It is only directly applicable in special rather restrictive conditions, notably for problems involving one independent variable. However I will discuss a number of special examples, in some of which the Morse theory really works, and others in which it clearly fails but where nevertheless some aspects appear still to survive. These examples include those of physical interest and it would be interesting to investigate these further. One can make a number of speculations in this direction.

The Penrose twistor theory converts problems of four-dimensional Riemannian geometry into complex analytic geometry of three dimensions. It applies whenever the Riemannian curvature is self-dual, in the sense that the Weyl tensor (the conformally invariant part of the Riemannian curvature) is self-dual. For a general exposition of this theory (in the positive definite case) see [Atiyah, Hitchin and Singer 1978]. Now on a Riemannian four-manifold there is a conformally invariant version of the Laplace operator (obtained by adding one-sixth of the scalar curvature of the usual Laplacian) and this has therefore a conformally invariant Green’s function (under appropriate global hypotheses). The purpose of this chapter is to show what corresponds to this Green’s function in the twistor theory. It turns out that we get a very well-known object in complex analytic geometry associated to the diagonal in \( Z \times Z \), where \( Z \) is the twistor space.

The three families of classical groups of linear transformations (complex, orthogonal, symplectic) give rise to the three great branches of differential geometry (complex analytic, Riemannian and symplectic). Complex analytic geometry derives most of its interest from complex algebraic geometry, while symplectic geometry provides the general framework for Hamiltonian mechanics.

These three classical groups “intersect” in the unitary group and the three branches of differential geometry correspondingly “intersect” in Kähler geometry, which includes the study of algebraic varieties in projective space. This is the basic reason why Hodge was successful in applying Riemannian methods to algebraic geometry in his theory of harmonic forms.

In many areas of differential equations topological methods can provide important qualitative information. This particularly applies to complicated problems where the number of variables is large. Examples will be given illustrating the scope and power of topological ideas.

For constant coefficient linear hyperbolic systems the fundamental solution is supported in the forward “light-cone”. For general systems this cone has many compartments and, in some of these (called lacunas) the fundamental solution may vanish. The determination of lacunas is a topological problem (solved originally by Petrovsky) involving the topology of multi-dimensional contour integrals in the complex domain.

For elliptic boundary value problems of Cauchy–Riemann or Dirac type the index, measuring the difference between the number of solutions of the problem and its adjoint, is a topological invariant which can be computed from the geometrical data. This has important applications to models in elementary particle physics.

For a periodic family of self-adjoint elliptic operators the spectral flow, counting the net number of eigenvalues which change sign over a period, is a topological invariant. This can be computed from the geometrical data and can be used to derive sharp bounds on gaps in the spectrum.

In non-linear PDE, “solitons” may have a topological origin, and soliton-interaction can be related to underlying topological features. This is illustrated by models in 2 and 3 spatial dimensions, following original ideas of Skyrme.

The relation between Geometry and Physics is a very ancient one going back to the earliest times, but in the modern period it is best exemplified by Einstein’s Theory of General Relativity. As is well known, Einstein interpreted gravitational force in terms of the curvature of space-time and Maxwell’s Theory of Electro-Magnetism was subsequently interpreted in a somewhat similar manner. At the presetnt time these geometrical ideas have been extended to incorporate the other fundamental forces of nature, the “weak” and “strong” forces that are encountered at the nuclear level. As a result we are witnessing now a remarkable interaction between mathematicians and physicists which has been extremely fruitful.

In Skyrme’s soliton model of baryons, a single Skyrmion has six degrees of freedom, so it is expected that two-Skyrmion dynamics at modest energies can be modelled by motion on a 12-dimensional space of Skyrme fields. A candidate for this space is generated by the gradient flow of the potential energy function, descending from the unstable, baryon number two, hedgehog solutions of the Skyrme field equation. An apparently very similar space is obtained by restricting the gradient flow to the Skyrme fields derived from \( \mathit{SU}(2) \) Yang–Mills instantons of charge two. On both of these spaces, one may quotient out by the group of translations and isospin rotations. Hartshome’s geometrical description of charge two instantons leads us to a conjecture for the global structure of the 6-dimensional quotient space. The conjectured structure is that of complex projective 3-space, with complex conjugate points on one projective plane identified and the real points in this plane removed.

Berry & Robbins, in their discussion of the spin-statistics theorem in quantum mechanics, were led to ask the following question. Can one construct a continuous map from the configuration space of \( n \) distinct particles in 3-space to the flag manifold of the unitary group \( U(n) \)? I shall discuss this problem and various generalizations of it. In particular, there is a version in which \( U(n) \) is replaced by an arbitrary compact Lie group. It turns out that this can be treated using Nahm’s equations, which are an integrable system of ordinary differential equations arising from the self-dual Yang–Mills equations. Our topological problem is therefore connected with physics in two quite different ways, once at its origin and once at its solution.

There is a very natural map from the configuration space of \( n \) distinct points in Euclidean 3-space into the flag manifold \( U(n)/U(1)^n \), which is compatible with the action of the symmetric group. The map is well defined for all configurations of points provided a certain conjecture holds, for which we provide numerical evidence. We propose some additional conjectures, which imply the first, and test these numerically. Motivated by the above map, we define a geometrical multi-particle energy function and compute the energy-minimizing configurations for up to 32 particles. These configurations comprise the vertices of polyhedral structures that are dual to those found in a number of complicated physical theories, such as Skyrmions and fullerenes. Comparisons with 2- and 3-particle energy functions are made. The planar restriction and the generalization to hyperbolic 3-space are also investigated.

We give a positive answer to the Berry–Robbins problem for any compact Lie group \( G \), i.e. we show the existence of a smooth \( W \)-equivariant map from the space of regular triples in a Cartan subalgebra to the flag manifold \( G/T \). This map is constructed via solutions to Nahm’s equations and it is compatible with the \( \mathit{SO}(3) \) action, where \( \mathit{SO}(3) \) acts on \( G/T \) via a regular homomorphism from \( \mathit{SU}(2) \) to \( G \). We then generalize this picture to include an arbitrary homomorphism from \( \mathit{SU}(2) \) to \( G \). This leads to an interesting geometrical picture which appears to be related to the Springer representation of the Weyl group and the work of Kazhdan and Lusztig on representations of Hecke algebras.

M. Atiyah and M. Hopkins: “A variant of \( K \)-theory: \( K_\pm \),” pp. 5–17 in Topology, geometry and quantum field theory (Oxford, 24–29 June 2002). Edited by U. Tillmann. Cambridge University Press, 2004. MR 2079369 Zbl 1090.19004 incollection

Topological \( K \)-theory has many variants which have been developed and exploited for geometric purposes. There are real or quaternionic versions, “real” \( K \)-theory in the sense of, equivariant \( K \)-theory and combinations of all these.

In recent years \( K \)-theory has found unexpected application in the physics of string theories and all variants of \( K \)-theory that had previously been developed appear to be needed. There are even variants, needed for the physics, which had previously escaped attention, and it is one such variant that is the subject of this paper.

This variant, denoted by \( K_{\pm}(X) \), was introduced by Witten in relation to “orientifolds”. The geometric situation concerns a manifold \( X \) with an involution \( \tau \) having a fixed sub-manifold \( Y \). On \( X \) one wants to study a pair of complex vector bundles \( (E^+, E^-) \) with the property that \( \tau \) interchanges them. If we think of the virtual vector bundle \( E^+ - E^- \), then \( \tau \) takes this into its negative, and \( K_{\pm}(X) \) is meant to be the appropriate K-theory of this situation.

In physics, \( X \) is a 10-dimensional Lorentzian manifold and maps \( \Sigma \to X \) of a surface \( \Sigma \) describe the world-sheet of strings. The symmetry requirements for the appropriate Feynman integral impose conditions that the putative \( K \)-theory \( K_{\pm}(X) \) has to satisfy.

The second author proposed a precise topological definition of \( K_{\pm}(X) \) which appears to meet the physics requirements, but it was not entirely clear how to link the physics with the geometry.

L’objecte d’aquest article és donar una perspectiva general de l’impacte científic i humà de Sir Michael Atiyah. La presentació de les principals idees i resultats amb què ha contribuït al coneixement matemàtic es complementa amb informacions sobre les persones que, per una raó o una altra, han tingut o tenen un paper rellevant en la seva trajectòria. El “racó matemàtic” (darrera secció) s’ha inclòs per facilitar, a les persones més motivades, una apreciació més detallada dels continguts matemàtics, i de física matemàtica, de l’obra d’Atiyah. Junt amb les referències bibliogràfiques, ens agradaria que aquest treball fos una invitació a explorar més profundament el seu lúcid pensament.

Inspired by soliton models, we propose a description of static particles in terms of Riemannian 4-manifolds with self-dual Weyl tensor. For electrically charged particles, the 4-manifolds are non-compact and asymptotically fibred by circles over physical 3-space. This is akin to the Kaluza–Klein description of electromagnetism, except that we exchange the roles of magnetic and electric fields, and only assume the bundle structure asymptotically, away from the core of the particle in question. We identify the Chern class of the circle bundle at infinity with minus the electric charge and, at least provisionally, the signature of the 4-manifold with the baryon number. Electrically neutral particles are described by compact 4-manifolds. We illustrate our approach by studying the Taub–Newman, Unti, Tamburino (Taub–NUT) manifold as a model for the electron, the Atiyah–Hitchin manifold as a model for the proton, \( \mathbb{C}P^2 \) with the Fubini–Study metric as a model for the neutron and \( S^4 \) with its standard metric as a model for the neutrino.
