Derived Categories of Coherent Sheaves and Triangulated Categories of Singularities
نویسنده
چکیده
In this paper we establish an equivalence between the category of graded D-branes of type B in Landau-Ginzburg models with homogeneous superpotential W and triangulated category of singularities of the fiber of W over zero. We also proved that the category of graded D-branes of type B in such LG-models is connected by a fully faithful functor with the derived category of coherent sheaves on the projective variety defined by the equation W = 0.

Graded B-branes on Simple Singularities
We prove the relation between the triangulated categories of graded B-branes on simple singularities and the derived categories of representations of Dynkin quivers. The proof is based on the theory of weighted projective lines by Geigle and Lenzing and Orlov’s theorem on the relation between triangulated categories of graded B-branes and the derived category of coherent sheaves.
متن کاملTriangulated 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 It seems that two different types of categories can be associated with singularities (or singularities of maps). Categories of the firs...
متن کاملRepresentations of Symplectic Reflection Algebras and Resolutions of Deformations of Symplectic Quotient Singularities
We give an equivalence of triangulated categories between the derived category of finitely generated representations of symplectic reflection algebras associated with wreath products (with parameter t = 0) and the derived category of coherent sheaves on a crepant resolution of the spectrum of the centre of these algebras.
متن کامل0 Mirror symmetry and actions of braid groups on derived categories
After outlining the conjectural relationship between the conjec-tural mirror symmetry programmes of Kontsevich and Strominger-Yau-Zaslow, I will describe some natural consequences of this which are proved from scratch in joint work with Mikhail Khovanov and Paul Seidel. Namely, actions of braid groups are found on derived categories of coherent sheaves, dual to Seidel's braid group of symplecti...
متن کاملRemarks on Generators and Dimensions of Triangulated Categories
In this paper we prove that the dimension of the bounded derived category of coherent sheaves on a smooth quasi-projective curve is equal to one. We also discuss dimension spectrums of these categories. 2000 Math. Subj. Class. 18E30, 14F05.
