The classical results in integral geometry found by Crofton, Poincaré, Cartan, and recently developed by Blaschke [1936, 1937] and his school, are mostly restricted to Eulidean spaces. It is the object of this paper to give the fundamental concepts of integral geometry in a general space of Klein, by which we mean a number space of \( n \) dimensions with a transitive \( r \)-parameter group \( G_r \) of transformations. The discussion is mainly based on Cartain’s theory of Lie’s groups [1937].

The paper is divided into three sections. In §1 we give a brief summary of Cartan’s theory of Lie’s groups with some results concerning the measures of geometrical elements. In §2 we define the incidence of the geometrical elements of different fields, which plays a fundamental rôle in all subsequent discussions. As applications of the general notions we give in the last section two formulas which are respectively generalizations of the well-known formulas of Crofton and Cauchy.

The notion of sphere bundles of H. Whitney [1941], [Stiefel 1936] has proved to be very fruitful in the applications of topology. So far in this theory an important rôle has been played by a class of topological invariants in the base space, called the characteristic cohomology classes and which can be regarded as generalizations of the Euler–Poincare characteristic. By assuming the base space to be a differentiable manifold with a Riemannian metric, on which the bundles of vectors and \( p \)-vectors are defined in a natural way, we shall give in this note various relations which exist between these topological invariants and certain differential invariants of the Riemannian manifold. In fact, the relations are such that the former are expressed as integrals of the latter. In the formulae the generalized Gauss–Bonnet formula due to Allendoerfer and Weil [1943] is included as a particular case.

It is well known that in three-dimensional elliptic or spherical geometry the so-called Clifford’s parallelism or parataxy has many interesting properties. A group-theoretic reason for the most important of these properties is the fact that the universal covering group of the proper orthogonal group in four variables is the direct product of the universal covering groups of two proper orthogonal groups in three variables. This last-mentioned property has no analogue for orthogonal groups in \( n \) (\( > 4 \)) variables. On the other hand, a knowledge of three-dimensional elliptic or spherical geometry is useful for the study of orientable Riemannian manifolds of four dimensions, because their tangent spaces possess a geometry of this kind. It is the purpose of this note to give a study of a compact orientable Riemannian manifold of four dimensions at each point of which is attached a three-dimensional spherical space. This necessitates a more careful study of spherical geometry than hitherto given in the literature, except, so far as the writer is aware, in a paper by E. Study [1907]. 0ur main result consists of two formulas, which express two topological invariants of a compact orientable differentiable manifold of four dimensions as integrals over the manifold of differential invariants constructed from a Riemannian metric previously given on the manifold. These two topological invariants have a linear combination which is the Euler–Poincaré characteristic.

In a previous paper [1944] we have given an intrinsic proof of the formula of Allendoerfer–Weil which generalizes to Riemannian manifolds of \( n \) dimensions the classical formula of Gauss–Bonnet for \( n=2 \). The main idea of the proof is to draw into consideration the manifold of unit tangent vectors which is intrinsically associated to the Riemannian manifold. Denoting by \( R^n \) the Riemannian manifold of dimension \( n \) and by \( M^{2n-1} \) the manifold of dimension \( 2n-1 \) of its unit tangent vectors, our proof has led, in the case that \( n \) is even, to an intrinsic differential form of degree \( n-1 \) (which we denoted by \( \Pi \)) in \( M^{2n-1} \). We shall introduce in this paper a differential form of the same nature for both even and odd dimensional Riemannian manifolds. We find that this differential form bears a close relation to the “Curvatura Integra” of a submanifold in a Riemannian manifold, because it will be proved that its integral over a closed submanifold of \( R^n \) is equal to the Euler–Poincaré characteristic of the submanifold. The method can be carried over to deduce relations between relative topological invariants of a submanifold of the manifold and differential invariants derived from the imbedding, and some remarks are to be added to this effect.

Let \( M \) be a closed oriented surface differentiably imbedded in a Euclidean space \( E \) of four dimensions. Let \( G \) denote the Grassmann manifold of oriented planes through a fixed point \( O \) of \( E \). It is well known that \( G \) is homeomorphic to the topological product \( S_1\times S_2 \) of two 2-spheres. By mapping each point \( P \) of \( M \) into the oriented plane through \( O \) parallel to the oriented tangent plane to \( M \) at \( P \), we define a mapping \( t:M\to G \). If \( M \), \( S_1 \), \( S_2 \) denote also the fundamental cycles of the respective manifolds and \( t_* \) denotes the homomorphism induced by \( t \), we have \[ t_*(M) \sim u_1S_1 + u_2S_2. \] In a recent paper [1949] Blaschke studied the situation described above by methods of differential geometry and proved that the sum \( u_1 + u_2 \) equals the Euler charateristic of \( M \). He also asserted that \( u_1 = u_2 \). The object of this note is to give a proof of this assertion, as well as a new proof of the theorem on \( u_1+u_2 \).

This paper will be concerned with some estimates on the lower bound of the dimension of the Euclidean space in which a compact Riemann manifold can be imbedded isometrically, if its curvatures satisfy certain conditions. Our basic geometrical idea is a very simple one. Denote by \( M \) a compact Riemann manifold of dimension \( n \) in a Euclidean space \( E \) of dimension \( n+N \), the Riemann metric on \( M \) being induced by the imbedding. Let \( O \) be a fixed point of \( E \). The distance \( OP \), \( p\in M \), is a continuous function in \( M \) and attains a maximum at a point \( P_0\in M \), since \( M \) is compact. It is intuitively clear that \( M \) will be “concave toward \( O \)” at \( P_0 \), so that there will be some restrictions on the Riemann curvature of \( M \) at \( P_0 \). If \( M \) is given abstractly, the imbedding will not be possible, if these restrictions are not fulfilled by the given Riemann metric at an of the points of \( M \). Actually, however, if the difference \( N \) of the dimensions of \( M \) and \( E \) is greater than one, the implication of this geometrical fact on the Riemann curvature of \( M \) is not very simple. The question leads to algebraic problems which probably do not have simple answers. We propose to give in this paper a few conclusions which can be drawn. It should be mentioned that the above geometrical idea has been used by Tompkins [1939] to prove that a locally flat compact Riemann manifold of dimension \( n \) cannot be isometrically imbedded in an Euclidean space of dimension \( 2n-1 \). Among other things this theorem will be generalized and the invariants entering in the problem geometrically interpreted. As for the differentiability assumptions we suppose our manifold and the imbedding to be of class \( \geq 4 \).

The geometrical nature of the theory of functions in one complex variable is a well-known fact and has been particularly emphasized by L. Ahlfors [1937]. It is also the most natural viewpoint, beause complex function thoery should be regarded as the first chapter of the theory of complex analytic mappings of complex manifolds and the classical study of value distributions is the study of the “size” of the image of a complex analytic mapping. We give in this paper a treatment, from a purely differential-geometric viewpoint, of complex analytic mappings of a Riemann surface (= one dimensional complex analytic manifold) into a compact Riemann surface. In the case when the first Riemann surface is a compact one with a finite number of points deleted, we derive defect relations which generalize the classical relations of Nevanlinna–Ahlfors. In a subsequent paper we will consider the case when the first Riemann surface is a compact one with a finite number of points and a finite number of disks deleted. The paper is written for differential geometers, so that concepts currently in use in differential geometry are freely used and a minimum of function theory will be required. The explicit models of the Gaussian plane or the unit disk are avoided.

The object of this paper is to make a beginning of the study of complex analytic mappings of the complex euclidean space of \( m \) dimensions into the complex projective space of the same dimension in the direction of a generalization of the classical theory of Picard–Borel for the one-dimensional case. The main geometrial conclusion of the Picard–Borel theory can be interpreted as a statement on the “size” of the image set. It is well-known that similar statements are not true in the case of higher dimensions. In fact, there are examples due to Bieberbach and Fatou in which the image set omits open subsets of the complex projective space [Bochner and Martin 1948, p. 45]. A proper approach to the theory should therefore begin with introducing the suitable concepts and draw conclusions on them. In a problem of this nature it is the general dimension of the original set which creates the difference from the classical theory. We take it to be the complex euclidean space. When the situation in this particular case becomes clear, various generalizations are possible.

Let \( z=z(x,y) \) be a \( C^2 \)-surface in euclidean three-space, defined over the disk \( x^2+y^2 < R^2 \) in the \( (x,y) \)-plane. Let \( H \) and \( K \) denote respectively its mean and Gaussian curvatures. In [1955] Heinz proved the folowing theorem:

If \( |H|\geq c > 0 \), then \( R\leq 1/c \). If \( K\geq c > 0 \), then \( R\leq 1/\sqrt{c} \). If \( K\leq -c < 0 \), then \( R\leq e(3/x)^{1/2} \). (\( c= \) const. in all cases).

The purpose of this paper is to extend this theorem to a hypersurface in an euclidean space of dimension \( m+1 \). Having the global problem in mind, we will consider an immersed hypersurface and establish, in so far as possible, the intermediary results in this general setting. In this sense some of our formulations are more general even in the classical case \( m=2 \).

In his dissertation Brian Smyth studied the complete hypersurfaces in a complex space-form whose induced metric is einsteinian and proved that these are either totally geodesic or certain hyperquadrics of the complex projective space. We wish to show in this note that the corresponding local theorem is true:

Let \( V \) be a kählerian manifold of dimension \( \geq 3 \) with constant holomorphic sectional curvature \( K \). Let \( f:M\to V \) be a holomorphically immersed hypersurface such that the induced metric is einsteinian. Then, if \( K\leq 0 \), \( M \) is totally geodesic. If \( K > 0 \) and \( V \) is identified with the complex projective space, \( M \) is either totally geodesic or a hypersphere.

We propose to define in this paper certain norms (or more precisely, semi-norms) on the homology groups of a complex manifold. They will be invariants of the complex strucgture and do not increase under holomorphic mappings. Their definitions depend on the bounded plurisubharmonic functions on the manifold and are modelled after the notion of harmonic length introduced by H. Landau and R. Osserman [1959–1960] for Riemann surfaces (= one-dimensional complex manifolds). It is possible to extend the definition to certain families of chains. In particular we get in this way an intrinsic pseudo-metric on the manifold which is closely related to that of Carathéodory [1927] and to one recently introduced by S. Kobayashi [1967].

Let \( X \) be a complex manifold of complex dimension \( n \) and \( \pi:E\to X \) a holomorphic vector bundle whose fiber dimension is also \( n \). On \( E \) we introduce a positive definite hermitian norm \( N \) and denote by \[ B^*(E) = \{e\in E\mid 0 < N(e)\} \] the subset of non-zero vectors of \( E \). Let \( c_n(E) \) be the Chern form of the hermitian structure (to be described again below). In [1965] we proved the theorem: There exists a real-valued form \( \rho \) of type \( (n-1, \) \( n-1) \) on \( B^*(E) \) such that \begin{equation*}\tag{1} \pi^* c_n(E) = \frac{dd^c}{4\pi}\rho. \end{equation*} In this paper we wish to give a proof of (1) based on an explicit construction. We will follow and extend a formalism developed in the real case by H. Flanders [1953]. It is possible that this formalism will be useful for later purposes.

Let \( M \) be an \( n \)-dimensional manifold which is minimally immersed in a unit sphere \( S^{n+p} \) of dimension \( n+p \). Let \( h \) be the second fundamental form of this immersion; it is a certain symmetric bilinear mapping \[ T_x\times T_x\to T_x^{\perp} \] for \( x\in M \), where \( T_x \) is the tangent space of \( M \) at \( x \) and \( T_x^{\perp} \) is the normal space to \( M \) at \( x \). We denote by \( S \) the square of the length of \( h \). It is known that if \( M \) is moreover compact, then \[ \int_M\Bigl(\Bigl(2-\frac{1}{p}\Bigr)S - n\Bigr)S\cdot *1\geq 0, \] where \( *1 \) denotes the volume element of \( M \) (Simons [1968]; a slightly more general formula will be proved in §§2 and 3). It follows that if \( S\leq n/(2-1/p) \) everywhere on \( M \), then either

\( S=0 \) (i.e., \( M \) is totally geodesic), or
\( S = n/(2-1/p) \).

The purpose of the present paper is to determine all minimal submanifolds \( M \) of \( S^{n+p} \) satisfying \( S = n/(2-1/p) \). The proof depends upon the results presented by the first named author in his lectures on minimal submanifolds in Berkeley in the Winter of 1968, in which an exposition of the work of Simons [1968] was made by the use of moving frames. To describe our result, we begin with examples of minimal submanifolds.

This paper proves various statements and propositions concerning fiber bundles with a Lie group, connections, curvature forms, and characteristic classes, and in particular concerning the recent work of Chern–Simons on secondary characteristic classes [1974] and of Cheeger–Simons on differential characters [1973]. Our main interest in this work is not so much in the characteristic classes but in the differential forms which represent them. Indeed, the aim of this paper is to study the duality properties of the characteristic forms, both the primary ones and the secondary ones. We begin by reviewing some basic notions. For general references, the reader is referred to [Chern 1972; Kobayashi and Nomizu 1963, 1969; Koszul 1973; Milnor and Stasheff 1974].

In recent years there have been extensive studies of evolution equations with soliton solutions, among which the most important ones are the Korteweg-deVries and sine-Gordon equations. We will show that the algebraic basis of these mathematical phenomena lies in Lie groups and their structure equations; their explicit solutions with special properties often give the evolution equations. The process is thus similar to the introdution of a “potential”. In fact, from \( \textrm{SL}(2;\mathbf{R}) \), the special linear group of all \( (2\times 2) \)-real unimodular matrices, one is led naturally to the KdV and MKdV (= modified Korteweg-deVries) equations of higher order. A Miura transformation exists between them. Following H. H. Chen [1976], this leads to the Bäcklund transformations of the KdV.

It is well known that there is a correspondence between solutions of the Sine-Gordon equation (SGE) \[ \frac{\partial^2\phi}{\partial x^2} - \frac{\partial^2\phi}{\partial t^2} = \sin\phi \] and the surfaces of constant curvature \( -1 \) in \( \mathbf{R}^3 \) (see below). The classical Bäcklund transformation of such surfaces furnishes a way to generate new solutions of the SGE from a given solution. This has received much attention in recent studies of the soliton solutions of the SGE, and the technique has been used successfully in the study of other non-linear evolution equations. In the first section of this paper we present a simple derivation of the classical Bäcklund theorem and its applications by using the method of moving frames.

Our main result concerns affine minimal surfaces. They arise as the solution of the variation problem for affine area. The corresponding Euler–Lagrange equation is a fourth order partial differential equation. In §2, we develop the basic properties of affine minimal surfaces. In §3 we study the transformation of affine surfaces by realizing them as the focal surfaces of a line congruence. The natural conditions that the congruence be a \( W \)-congruence and that the affine normals at corresponding points be parallel lead to the conclusion that both surfaces are affine minimal. This is the content of Theorem 4, the main result of our paper. As in the classical case, the Theorem leads to the construction of new affine minimal surfaces from a given one by the solution of a completely integrable system of first order partial differential equations.

In a recent paper [1980] M. Kuranishi gave a new proof of a theorem of Kashiwara–Kawai–Sato and Boutet de Monvel that any non-degenerate \( CR \)-system on a conic neighborhood of its characteristic is conjugate under a canonical transformation to the \( CR \)-sstem derived from teh Heisenberg structure. The theorem is clearly related to the classical theorem of Sophus Lie that a second-order differential equation \[ z^{\prime\prime} = F(x,z,z^{\prime}) \] in the \( (x,z) \)-plane has no local invariant under contact transformations. In this paper we shall give a generalization of Lie’s theorem to high dimensions and apply it to \( CR \) stuctures. Various notions of equivalence of \( CR \)-structures will be discussed.

In this paper we will develop, by moving frames, the basic formulas and some results on minimal surfaces, both in a Riemannian and in a Kählerian manifold. When the ambient Riemannian manifold is of constant curvature, we will show that a quartic form defined in a natural way from the second fundamental form is holomorphic, relative to the underlying complex structure of the surface. This will be applied to the study of minimal surfaces on the unit 4-sphere \( S^4(1) \). We will show how to derive by this approach a theorem of R. Bryant that a compact Riemann surface can be conformally immersed as a minimal surface in \( S^4(1) \).

When the ambient space is a Kählerian manifold, the first-order jet of the surface defines a scalar invariant, which is the Kähler form divided by the element of area of the surface. This will be used to normalize the frames attached to the surface. When the surface is minimal, an invariant cubic form appears naturally. We will show that it is holomorphic, if the ambient Kählerian manifold is of constant holomorphic sectional curvature. This will be applied to the complex projective plane \( P_2(\mathbf{C}) \) (with the Fubini–Study metric), to give a family of minimal surfaces in \( P_2(\mathbf{C}) \), and all its minimal two-spheres. A determination of all the minimal 2-spheres in \( P_n(\mathbf{C}) \) method has been carried out by the second author [1982]. This latter problem was first studied by Din–Zakrewski [1980] and a mathematician’s treatment was given by Eels–Wood [1983].

Let \( G(k,n) \) be the Grassmann manifold of all \( C_k \) in \( C_n \), the complex spaces of dimensions \( k \) and \( n \), respectively, or, what is the same, the manifold of all projective spaces \( P_{k-1} \) in \( P_{n-1} \), so that \( G(1,n) \) is the complex projective space \( P_{n-1} \) itself. We study harmonic maps of the two-dimensional sphere \( S^2 \) into \( G(k,n) \). The case \( k=1 \) has been the subject of investigation by several authors [see, for example, Din, A. M. & Zakrzewski, W. J. (1980) Nucl. Phys. B 174, 397–406; Eells, J. & Wood, J. C. (1983) Adv. Math. 49, 217–263; and Wolfson, J. G. Trans. Am. Math. Soc., in press]. The harmonic maps \( S^2\to G(2,4) \) have been studied by Ramanathan [Ramanathan, J. (1984) J. Differ. Geom. 19, 207–219]. We shall describe all harmonic maps \( S^2\to G(2,n) \). The method is based on several geometrical constructions, which lead from a given harmonic map to new harmonic maps, in which the image projective spaces are related by “fundamental collineations.” The key result is the degeneracy of some fundamental collineations, which is a global consequence, following from the fact that the domain manifold is \( S^2 \). The method extends to \( G(k,n) \).

Shiing-Shen Chern was born on October 26th, 1911, in Jia Xin, Chekiang Province, in China. His father practised law and worked for the government. At Fu Luen Middle School in Tsientsin he first showed his mathematical ability by doing all the exercises in classical English textbooks on algebra and trigonometry, and then went at the age of fifteen to Nankai University — a one-man Department run by Li-Fu Chiang, a student of Coolidge. As a result he studied a great deal of geometry, reading Coolidge, Salmon, Castelnuovo and Staude. He then became a postgraduate in 1930 at Tsinghua University in Beijing (or Peiping as it was then called) and came under the influence of Dan Sun, one of the few mathematicians in China writing research papers. During this period he became seriously interested in Sun’s subject, projective differential geometry, and studied in detail the works of Wilhelm Blaschke. It was also at Tsinghua that he met his wife Shih-Ning, the daughter of a professor. After Blaschke paid a visit to Tsinghua in 1932 and lectured on differential-geometric invariants, Chern won a fellowship to study with him in Hamburg for two years. In 1936 he received his DSc there for work on the theory of webs. While in Hamburg, he also attended the lectures of Kähler on what is now called Cartan–Kähler theory, and the following year he spent in Paris studying with Cartan himself.

Shiing-Shen Chern was an editor of our journal Results in Mathematics from 1984 to 2004, the year he passed away at Tianjin. This article honors one of the greatest mathematicians of the twentieth century, in particular remembering his studies at Hamburg University during the years 1934–1936. This period strongly influenced his mathematical work and was decisive for his later career. We survey the situation of the Department of Mathematics there, Chern’s studies, his visits to Germany in later years, his honours and awards from German institutions, and finally exemplarily his influence on the next generations of Chinese mathematicians studying in Germany.
