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