Triangulated categories of singularities and D-branes in Landau-Ginzburg models

arXiv:math/0302304

Abstract

In spite of physics terms in the title, this paper is purely mathematical. Its purpose is to introduce triangulated categories related to singularities of algebraic varieties and establish a connection of these categories with D-branes in Landau-Ginzburg models.
