The present paper investigates the relationships between the particle-like solutions of classical nonlinear translationally invariant equations and the particles in quantum field theory. Scattering in the quantum and classical cases is also compared. The relationships are traced, in particular, for an exactly solvable model, a nonlinear, one-dimensional Schrödinger equation.

If the action functional is determined uniquely by its symmetry properties, we say that this functional is perfect. We study the perfect functionals in the framework in which the space and field variables are on equal footing. This study leads to the natural multidimensional generalizations of supergravity.

The supergravity torsion and curvature constraints are shown to be a particular case of constraints arising in a general geometrical situation. For this purpose, a theorem is proved which describes the necessary and sufficient conditions that the given geometry can be realized on a surface as one induced by the geometry of the ambient space. The proof uses the theory of nonlinear partial differential equations in superspace, Spencer cohomologies, etc. This theorem generalizes various theorems, well known in mathematics (e.g., the Gauss–Codazzi theorem), and may be of its own interest.

The supermoduli space and the measure on this space arising from fermionic string theory are studied. Analytic properties of this measure are analyzed. Our considerations, combined with previous results by Voronov, give an expression of string measure through analytic superfields and their zeros. The behavior of measure in the vicinity of the boundary of moduli space is studied on the base of this expression.

The main facts about complex curves are generalized to superconformal manifolds. The results thus obtained are relevant to the fermion string theory and, in particular, they are useful for computation of determinants of super laplacians which enter the string partition function.

Physicists hope that the Green–Schwarz superstring theory describes all interactions existing in the Nature. However the verification of this conjecture is connected with very difficult and very interesting mathematical problems. We consider here only some problems arising in the Polyakov approach to the fermionic string. (Fermionic string is closely related with the Green–Schwarz superstring.) We explain the connection between string theory and superconformal geometry, the origin of string measure on superconformal moduli space and analytic properties of this measure, the construction of universal moduli space and the expression of string measure in terms of super \( \tau \) -function etc. The lecture is based on the papers [Baranov and Schwarz 1985; Baranov, Frolov and Schwarz 1987; Baranov and Schwarz 1987; Schwarz 1988; Rosly, Schwarz and Voronov 1988; Rosly, Schwarz and Voronov 1989; Schwarz 1989; Dolgikh and Schwarz 1990; Dolgikh, Rosly and Schwarz 1990; Baranov, Frolov and Schwarz 1989]. The results concerning the measure on the moduli space of \( N = 2 \) superconformal manifolds are new.

The space of all solutions to the string equation of the symmetric unitary one-matrix model is determined. It is shown that the string equation is equivalent to simple conditions on points \( V_1 \) and \( V_2 \) in the big cell \( \mathrm{Gr}^{(0)} \) of the Sato Grassmannian \( \mathrm{Gr} \) . This is a consequence of a well-defined continuum limit in which the string equation has the simple form \( [\mathscr{P},\mathscr{Q}_{-}] = 1 \) , with \( \mathscr{P} \) and \( \mathscr{Q}_{-} \) \( 2{\times} 2 \) matrices of differential operators. These conditions on \( V_1 \) and \( V_2 \) yield a simple system of first order differential equations whose analysis determines the space of all solutions to the string equation. This geometric formulation leads directly to the Virasoro constraints \( L_n \) (\( n\geq 0 \) ), where \( L_n \) annihilate the two modified-KdV \( \tau \) -functions whose product gives the partition function of the Unitary Matrix Model.

The results are applied to the analysis of the Batalin–Vilkovisky approach to the quantization of gauge theories. In particular the semiclassical approximation in this approach is expressed in terms of Reidemeister torsion.

Lian and Zuckerman proved that the homology of a topological chiral algebra can be equipped with the structure of a BV-algebra; i.e., one can introduce a multiplication, an odd bracket, and an odd operator \( \Delta \) having the same properties as the corresponding operations in Batalin–Vilkovisky quantization procedure. We give a simple proof of their results and discuss a generalization of these results to the non chiral case. To simplify our proofs we use the following theorem giving a characterization of a BV-algebra in terms of multiplication and an operator \( \Delta \) : If \( \mathcal{A} \) is a supercommutative, associative algebra and \( \Delta \) is an odd second order derivation on \( \mathcal{A} \) satisfying \( \Delta^2 = 0 \) , one can provide \( \mathcal{A} \) with the structure of a BV-algebra.

We consider generalizations of the Vieta formula (relating the coefficients of an algebraic equation to the roots) to the case of equations whose coefficients are order-\( k \) matrices.
Specifically, we prove that if \( X_1,\dots \) , \( X_n \) are solutions of an algebraic matrix equation
\[ X^n + A_1 X^{n-1} + \cdots + A_n = 0 ,\]
independent in the sense that they determine the coefficients \( A_1,\dots \) , \( A_n \) , then the trace of \( A_1 \) is the sum of the traces of the \( X_i \) , and the determinant of \( A_n \) is, up to a sign, the product of the determinants of the \( X_i \) . We generalize this to arbitrary rings with appropriate structures.
This result is related to and motivated by some constructions in non-commutative geometry.

Let us consider an \( A_{\infty} \) algebra with an invariant inner product. The main goal of this paper is to classify the infinitesimal deformations of this \( A_{\infty} \) algebra preserving the inner product and to apply this result to the construction of homology classes on the moduli spaces of algebraic curves. With this aim, we define cyclic cohomology of an \( A_{\infty} \) algebra and show that it classifies the deformations we are interested in. To make the reading of our paper more independent of other works, we include a short review of Hochschild and cyclic cohomology of associative algebras, and explain the definition of \( A_{\infty} \) algebras.

We study a topological sigma-model (\( A \) -model) in the case when the target space is an \( (m_0|m_1) \) -dimensional supermanifold. We prove under certain conditions that such a model is equivalent to an \( A \) -model having an \( (m_0 {-} m_1) \) -dimensional manifold as a target space. We use this result to prove that in the case when the target space of \( A \) -model is a complete intersection in a toric manifold, this \( A \) -model is equivalent to an \( A \) -model having a toric supermanifold as a target space.

In Batalin–Vilkovisky formalism, a classical mechanical system is specified by means of a solution to the classical master equation . Geometrically, such a solution can be considered as a \( QP \) -manifold, i.e. a supermanifold equipped with an odd vector field \( Q \) obeying \( \{Q,Q\} = 0 \) and with \( Q \) -invariant odd symplectic structure. We study geometry of \( QP \) -manifolds. In particular, we describe some construction of \( QP \) -manifolds and prove a classification theorem (under certain conditions).
We apply these geometric constructions to obtain in a natural way the action functionals of two-dimensional topological sigma-models and to show that the Chern–Simons theory in BV-formalism arises as a sigma-model with target space \( \Pi\mathcal{G} \) . (Here \( \mathcal{G} \) stands for a Lie algebra and \( \Pi \) denotes parity inversion.)

We study toroidal compactification of Matrix theory, using ideas and results of non-commutative geometry. We generalize this to compactification on the noncommutative torus, explain the classification of these backgrounds, and argue that they correspond in supergravity to tori with constant background three-form tensor field. The paper includes an introduction for mathematicians to the IKKT formulation of Matrix theory and its relation to the BFSS Matrix theory.

The infinite-dimensional Grassmannian manifold contains moduli spaces of Riemann surfaces of all genera. This well known fact leads to a conjecture that non-perturbative string theory can be formulated in terms of the Grassmannian. We present new facts supporting this hypothesis. In particular, it is shown that Grassmannians can be considered as generalized moduli spaces; this statement permits us to define corresponding “string amplitudes” (at least formally). One can conjecture that it is possible to explain the relation between non-perturbative and perturbative string theory by means of localization theorems for equivariant cohomology; this conjecture is based on the characterization of moduli spaces, relevant to string theory, as sets consisting of points with large stabilizers in certain groups acting on the Grassmannian. We describe an involution on the Grassmannian that could be related to \( S \) -duality in string theory.

We prove that compactifications on Morita equivalent tori are in some sense physically equivalent. This statement can be considered as a generalization of non-classical \( SL(2\mathbb{Z})_N \) duality conjectured by Connes, Douglas and Schwarz for compactifications on two-dimensional non-commutative tori.

We show that the resolution of moduli space of ideal instantons parameterizes the instantons on noncommutative \( \mathbb{R}^4 \) . This moduli space appears to be the Higgs branch of the theory of \( k \) \( D0 \) -branes bound to \( N \) \( D4 \) -branes by the expectation value of the \( B \) field. It also appears as a regularized version of the target space of supersymmetric quantum mechanics arising in the light cone description of \( (2,0) \) superconformal theories in six dimensions.

One can describe an \( n \) -dimensional noncommutative torus by means of an antisymmetric \( n{\times} n \) matrix \( \theta \) . We construct an action of the group \( SO(n,n|\mathbb{Z}) \) on the space of \( n{\times} n \) antisymmetric matrices and show that, generically, matrices belonging to the same orbit of this group give Morita equivalent tori. Some applications to physics are sketched.

We study gauge theories on non-commutative tori. It has been proved that Morita equivalence of non-commutative tori leads to a physical equivalence (\( SO(d,d|\mathbb{Z}) \) -duality) of the corresponding gauge theories [Nucl. Phys. B 534 (1998) 720]. We calculate the energy spectrum of maximally supersymmetric BPS states in these theories and show that this spectrum agrees with the . The relation of our results with those of recent calculations is discussed.

Even though the two have the same structure group, they differ in their action since Morita equivalence makes crucial use of an additional modulus on the NCSYM side, the constant abelian magnetic background. In this paper, we reanalyze and clarify the correspondence between M(atrix) theory and NCSYM, and provide two resolutions of this puzzle. In the first of them, the standard map is kept and the extra modulus is ignored, but the anomalous transformation is offset by the M(atrix) theory “rest term”. In the second, the standard map is modified so that the duality transformations agree, and a \( SO(d) \) symmetry is found to eliminate the spurious modulus. We argue that this is a true symmetry of supersymmetric Born–Infeld theory on a non-commutative torus, which allows to freely trade a constant magnetic background for non-commutativity of the base-space. We also obtain a BPS mass formula for this theory, invariant under \( T \) -duality, \( U \) -duality, and continuous \( SO(d) \) symmetry.

We develop the theory of connections on modules over \( \mathcal{Q} \) -algebras and prove a general duality theorem for gauge theories on such modules. This theorem contains as a simplest case \( SO(d,d,\mathbb{Z}) \) -duality of gauge theories on noncommutative tori.

We analyze the perturbation series for the noncommutative eigenvalue problem \( AX = X\lambda \) , where \( \lambda \) is an element of a noncommutative ring, \( A \) is a matrix, and \( X \) is a column vector with entries from this ring. As a corollary, we obtain a theorem about the structure of perturbation series for \( \operatorname{Tr}x^r \) where \( x \) is a solution of a noncommutative algebraic equation (for \( r = 1 \) this theorem was proved by Aschieri, Brace, Morariu, and Zumino (hep-th/0003228), and used to study the Born–Infeld Lagrangian for the gauge group \( U(1)^k \) ).

It was shown by A. Connes, M. Douglas and A. Schwarz that noncommutative tori arise naturally in consideration of toroidal compactifications of M(atrix) theory. A similar analysis of toroidal \( \mathbb{Z}_2 \) orbifolds leads to the algebra \( B_{\theta} \) that can be defined as a crossed product of noncommutative torus and the group \( \mathbb{Z}_2 \) . Our paper is devoted to the study of projective modules over \( B_{\theta} \) (\( \mathbb{Z}_2 \) -equivariant projective modules over a noncommutative torus). We analyze the Morita equivalence (duality) for \( B_{\theta} \) algebras working out the two-dimensional case in detail.

We discuss instantons on noncommutative four-dimensional Euclidean space. In the commutative case one can consider instantons directly on Euclidean space, then we should restrict ourselves to the gauge fields that are gauge equivalent to the trivial field at infinity. However, technically it is more convenient to work on the four-dimensional sphere. We will show that the situation in the noncommutative case is quite similar. One can analyze instantons taking as a starting point the algebra of smooth functions vanishing at infinity, but it is convenient to add a unit element to this algebra (this corresponds to a transition to a sphere at the level of topology). Our approach is more rigorous than previous considerations; it seems that it is also simpler and more transparent. In particular, we obtain the ADHM equations in a very simple way.

Ordinary theta functions can be considered as holomorphic sections of line bundles over tori. We show that one can define generalized theta functions as holomorphic elements of projective modules over noncommutative tori (theta vectors). The theory of these new objects is not only more general, but also much simpler than the theory of ordinary theta-functions. It seems that the theory of theta vectors should be closely related to Manin’s theory of quantized theta functions, but we don’t analyze this relation.

We study finitely generated projective modules over noncommutative tori. We prove that for every module \( E \) with constant curvature connection the corresponding element \( [E] \) of the K-group is a generalized quadratic exponent and, conversely, for every positive generalized quadratic exponent \( \mu \) in the K-group one can find such a module \( E \) with constant curvature connection that \( [E] = \mu \) . In physical words we give necessary and sufficient conditions for existence of \( 1/2 \) BPS states in terms of topological numbers.

Noncommutative geometry is based on an idea that an associative algebra can be regarded as “an algebra of functions on a noncommutative space”. The major contribution to noncommutative geometry was made by A. Connes, who, in particular, analyzed Yang–Mills theories on noncommutative spaces, using important notions that were introduced in his papers (connection, Chern character, etc). It was found recently that Yang–Mills theories on noncommutative spaces appear naturally in string/M-theory; the notions and results of noncommutative geometry were applied very successfully to the problems of physics.
In this paper we give a mostly self-contained review of some aspects of M(atrix) theory, of Connes’ noncommutative geometry and of applications of noncommutative geometry to M(atrix) theory. The topics include introduction to BFSS and IKKT matrix models, compactifications on noncommutative tori, a review of basic notions of noncommutative geometry with a detailed discussion of noncommutative tori, Morita equivalence and \( SO(d,d|\mathbb{Z}) \) -duality, an elementary discussion of noncommutative orbifolds, noncommutative solitons and instantons. The review is primarily intended for physicists who would like to learn some basic techniques of noncommutative geometry and how they can be applied in string theory and to mathematicians who would like to learn about some new problems arising in theoretical physics.
The second part of the review devoted to solitons and instantons on noncommutative Euclidean space is almost independent of the first part.

Following Lett. Math. Phys. 50 (1999) 309, we introduce a notion of \( \mathcal{Q} \) -algebra that can be considered as a generalization of the notion of \( \mathcal{Q} \) -manifold (a supermanifold equipped with an odd vector field obeying \( \{Q,Q\} = 0 \) ). We develop the theory of connections on modules over \( \mathcal{Q} \) -algebras and prove a general duality theorem for gauge theories on such modules. This theorem containing as a simplest case \( SO(d,d,\mathbb{Z}) \) -duality of gauge theories on noncommutative tori can be applied also in more complicated situations. We show that \( \mathcal{Q} \) -algebras appear naturally in Fedosov construction of formal deformation of commutative algebras of functions and that similar \( \mathcal{Q} \) -algebras can be constructed also in the case when the deformation parameter is not formal.

We say that a function \( F(\tau) \) obeys WDVV equations, if for a given invertible symmetric matrix \( \eta^{\alpha \beta} \) and all \( \tau \in \mathcal{T} \subset \mathbb{R}^n \) , the expressions
\[ c_{\beta\gamma}^{\alpha}(\tau) = \eta^{\alpha\lambda}\partial_{\lambda}\partial_{\beta}\partial_{\gamma}F \]
can be considered as structure constants of commutative associative algebra; the matrix \( \eta_{\alpha \beta} \) inverse to \( \eta^{\alpha \beta} \) determines an invariant scalar product on this algebra. A function \( x^{\alpha}(z,\tau) \) obeying
\[ \partial_{\alpha}\partial_{\beta} \,x^{\gamma}(z,\tau) = z^{-1}c_{\alpha\beta}^{\epsilon}\partial_{\epsilon}\,x^{\gamma}(z,\tau) \]
is called a calibration of a solution of WDVV equations. We show that there exists an infinite-dimensional group acting on the space of calibrated solutions of WDVV equations (in different form such a group was constructed in [Givental 2004]. We describe the action of Lie algebra of this group.

We conjecture a relation between the \( \mathfrak{sl}(N) \) knot homology, recently introduced by Khovanov and Rozansky, and the spectrum of BPS states captured by open topological strings. This conjecture leads to new regularities among the \( \mathfrak{sl}(N) \) knot homology groups and suggests that they can be interpreted directly in topological string theory. We use this approach in various examples to predict the \( \mathfrak{sl}(N) \) knot homology groups for all values of \( N \) . We verify that our predictions pass some non-trivial checks.

We use the notion of the twisted de Rham cohomology to give meaning to an integral of the form
\[ \int g(x) e^{f(x)} dx \]
over an arbitrary ring. We discuss also a definition of a family of integrals and some properties of the above homological definition of the integral. We show how to use the twisted de Rham cohomology to define the Frobenius map on the \( p \) -adic cohomology. Finally, we consider two-dimensional topological quantum field theories with general coefficients.

We give complete answers for (non-extended) supersymmetry in all dimensions \( \leq 11 \) . For dimensions \( D = 10,\,11 \) we describe also the cohomology of reduction of supersymmetry Lie algebra to lower dimensions. Our methods can be applied to extended supersymmetry Lie algebras.

We study supersymmetric and super Poincaré invariant deformations of tendimensional super Yang–Mills theory and of its dimensional reductions. We describe all infinitesimal super Poincaré invariant deformations of equations of motion of ten-dimensional super Yang–Mills theory and deformations of the reduction to a point. We also discuss how these infinitesimals can be extended to formal deformations. Our methods are based on homological algebra, in particular, on the theory of \( L_{\infty} \) and \( A_{\infty} \) algebras. The exposition of this theory as well as of some basic facts about Lie algebra homology and Hochschild homology is given in appendices.

In the study of the Type II superstring, it is useful to consider the BRST complex associated to the sum of two pure spinors. The cohomology of this complex is an infinite-dimensional vector space. It is also a finite-dimensional algebra over the algebra of functions of a single pure spinor. In this paper we study the multiplicative structure.

We are solving for the case of flat superspace some homological problems that were formulated by Berkovits and Howe. (Our considerations can be applied also to the case of supertorus.) These problems arise in the attempt to construct integrals invariant with respect to supersymmetry. They appear also in other situations, in particular, in the pure spinor formalism in supergravity.

One says that a pair \( (P,Q) \) of ordinary differential operators specify a quantum curve if \( [P,Q] = \hbar \) . If a pair of difference operators \( (K,L) \) obey the relation
\[ KL = qLK \quad \text{where }q = e^{\hbar} ,\]
we say that they specify a discrete quantum curve.
This terminology is prompted by well known results about commuting differential and difference operators, relating pairs of such operators with pairs of meromorphic functions on algebraic curves obeying some conditions.
The goal of this paper is to study the moduli spaces of quantum curves. We will relate the moduli spaces for different \( \hbar \) . We will show how to quantize a pair of commuting differential or difference operators (i.e., to construct the corresponding quantum curve or discrete quantum curve).

Motivated by their role for integrality and integrability in topological string theory, we introduce the general mathematical notion of “\( s \) -functions” as integral linear combinations of poly-logarithms. 2-functions arise as disk amplitudes in Calabi–Yau D-brane backgrounds and form the simplest and most important special class. We describe \( s \) -functions in terms of the action of the Frobenius endomorphism on formal power series and use this description to characterize 2-functions in terms of algebraic K-theory of the completed power series ring. This characterization leads to a general proof of integrality of the framing transformation, via a certain orthogonality relation in K-theory. We comment on a variety of possible applications. We here consider only power series with rational coefficients; the general situation when the coefficients belong to an arbitrary algebraic number field is treated in a companion paper.

We formulate axioms of conformal theory (CT) in dimensions \( > 2 \) modifying Segal’s axioms for two-dimensional CFT. (In the definition of higher-dimensional CFT, one includes also a condition of existence of energy-momentum tensor.) We use these axioms to derive the AdS/CT correspondence for local theories on AdS. We introduce a notion of weakly local quantum field theory and construct a bijective correspondence between conformal theories on the sphere \( S^d \) and weakly local quantum field theories on \( H^{d+1} \) that are invariant with respect to isometries. (Here \( H^{d+1} \) denotes hyperbolic space = Euclidean AdS space.) We give an expression of AdS correlation functions in terms of CT correlation functions. The conformal theory has conserved energy-momentum tensor iff the AdS theory has graviton in its spectrum.

We say that a formal power series \( \sum a_n z^n \) with rational coefficients is a 2-function if the numerator of the fraction \( a_{n/p} - p^2 a_n \) is divisible by \( p^2 \) for every prime number \( p \) . One can prove that 2-functions with rational coefficients appear as building block of BPS generating functions in topological string theory. Using the Frobenius map we define 2-functions with coefficients in algebraic number fields. We establish two results pertaining to these functions. First, we show that the class of 2-functions is closed under the so-called framing operation (related to compositional inverse of power series). Second, we show that 2-functions arise naturally in geometry as \( q \) -expansion of the truncated normal function associated with an algebraic cycle extending a degenerating family of Calabi–Yau 3-folds.

In maximally supersymmetric four-dimensional gauge theories planar on-shell diagrams are closely related to the positive Grassmannian and the cell decomposition of it into the union of so called positroid cells. (This was proven by N. Arkani-Hamed, J. Bourjaily, F. Cachazo, A. Goncharov, A. Postnikov, and J. Trnka.) We establish that volume forms on positroids used to express scattering amplitudes can be \( q \) -deformed to Hochschild homology classes of corresponding quantum algebras. The planar amplitudes are represented as sums of contributions of some set of positroid cells; we quantize these contributions. In classical limit our considerations allow us to obtain explicit formulas for contributions of positroid cells to scattering amplitudes.

We study the scattering of particles and quasiparticles in the framework of algebraic quantum field theory. The main novelty is the construction of inclusive scattering matrix related to inclusive cross-sections. The inclusive scattering matrix can be expressed in terms of generalized Green functions by a formula similar to the LSZ formula for the conventional scattering matrix.
The consideration of inclusive scattering matrix is necessary in quantum field theory if a unitary scattering matrix does not exist (if the theory does not have particle interpretation). It is always necessary if we want to consider collisions of quasiparticles.

The quantum theory can be formulated in the language of positive functionals on Weyl or Clifford algebra (\( L \) -functionals). It is shown that this language gives simple understanding of diagrams of Keldysh formalism (that coincide in our case with the diagrams of thermo-field dynamics). The matrix elements of the scattering matrix in the formalism of \( L \) -functionals are related to inclusive cross-sections, therefore we suggest the name “inclusive scattering matrix” for this notion. The inclusive scattering matrix can be expressed in terms of on-shell values of generalized Green functions. This notion is necessary if we want to analyze collisions of quasiparticles.

Abstract
BibTeX
We show how to formulate quantum theory taking as a starting point the set of states (geometric approach). We discuss the equations of motion and the formulas for probabilities of physical quantities in this approach. A heuristic proof of decoherence in our setting is used to justify the formulas for probabilities. We show that quantum theory can be obtained from classical theory if we restrict the set of observables. This remark can be used to construct models with any prescribed group of symmetries; one can hope that this construction leads to new interesting models that cannot be build in the conventional framework.
The geometric approach can be used to formulate quantum theory in terms of Jordan algebras, generalizing the algebraic approach to quantum theory. The scattering theory can be formulated in geometric approach.
