Gromov-Witten classes, quantum cohomology, and enumerative geometry
The paper is devoted to the mathematical aspects of topological quantum field theory and its applications to enumerative problems of algebraic geometry. In particular, it contains an axiomatic
The theme of this paper is the correspondence between classical modular forms and pseudodifferential operators (ΨDO’s) which have some kind of automorphic behaviour. In the simplest case, this
Multiparametric quantum deformation of the general linear supergroup
In the work L. D. Faddeev and his collaborators, and subsequently V. G. Drinfeld, M. Jimbo, S. L. Woronowicz, a new class of Hopf algebras was constructed. They can be considered as one-parametric
Relations Between the Correlators of the Topological Sigma-Model Coupled to Gravity
Abstract:We prove a new recursive relation between the correlators ¶, which together with known relations allows one to express all of them through the full system of Gromov–Witten invariants in the
A supersymmetric extension of the Kadomtsev-Petviashvili hierarchy
An extension of the Kadomtsev-Petviashvili hierarchy by odd variables is given. Conservation laws and formal integrability are proved.
Semi)simple exercises in quantum cohomology
The paper is dedicated to the study of algebraic manifolds whose quantum cohomology or a part of it is a semisimple Frobenius manifold. Theorem 1.8.1 says, roughly speaking, that the sum of
Real multiplication and noncommutative geometry (ein Alterstraum)
Preface. Abel’s name is associated with a number of key notions of modern mathematics, such as abelian varieties, Abel’s integrals, etc. Moreover, it became almost synonymous with the idea of
