Perverse Sheaves on a Triangulated Space
نویسنده
چکیده
The goal of this note is to prove that the category of perverse sheaves constructible with respect to a triangulation is Koszul (i.e. equivalent to the category of finite-dimensional representations of a Koszul algebra). This result was conjectured by M. Vybornov in the framework of the general theory of cellular perverse sheaves due to R. MacPherson [4], [5]. Acknowledgments. I am grateful to A. Beilinson and L. Positselski for useful discussions and valuable remarks.

Sheaves on Triangulated Spaces and Koszul Duality
Let X be a finite connected simplicial complex, and let δ be a perversity (i.e., some function from integers to integers). One can consider two categories: (1) the category of perverse sheaves cohomologically constructible with respect to the triangulation, and (2) the category of sheaves constant along the perverse simplices (δ-sheaves). We interpret the categories (1) and (2) as categories of...
متن کاملAn Introduction to Perverse Sheaves and Character Sheaves
After a brief review of derived categories, triangulated categories and t-structures, we shall consider the bounded derived category D(X,R) of the category of étale sheaves of R-modules on X (a k-scheme of finite type), where R is an l-torsion ring with l a prime number distinct from the characteristic of the field k. We shall construct a t-structure on the (triangulated) full subcategory D c(X...
متن کاملPerverse Coherent Sheaves on Blow-up. Ii. Wall-crossing and Betti Numbers Formula
This is the second of series of papers studyig moduli spaces of a certain class of coherent sheaves, which we call stable perverse coherent sheaves, on the blow-up p : X̂ → X of a projective surface X at a point 0. The followings are main results of this paper: a) We describe the wall-crossing between moduli spaces caused by twisting of the line bundle O(C) associated with the exceptional diviso...
متن کاملPerverse Sheaves on Image Multiple Point Spaces
Using multiple point spaces some new examples of perverse sheaves on images of maps are described. Furthermore, suppose f : X ! Y is a nite and proper map of complex analytic manifolds of dimension n and n + 1 such that every multiple point space is non-singular and has the dimension expected of a generic map. Then we can describe the composition series for the constant sheaf on the image in th...
متن کاملPerverse Sheaves and Ic-modules. the Koszul Case
For a stratified topological space we introduce the category of (mixed) IC-modules which are linear algebra devices with the relations described by the equation d = 0. We prove that the category of (mixed) IC-modules is equivalent to the category of (mixed) perverse sheaves for flag varieties.
