Perverse Schobers

  title={Perverse Schobers},
  author={Mikhail M. Kapranov and Vadim Schechtman},
The notion of a perverse sheaf, introduced in [BBD], has come to play a central role in algebraic geometry and representation theory. In particular, appropriate categories of perverse sheaves provide “categorifications” of various representation spaces, these spaces being recovered as the Grothedieck groups of the categories. The goal of this paper is to suggest the possibility of categorifying the very concept of a perverse sheaf. In other words, we propose to develop a theory of perverse…

A class of perverse schobers in Geometric Invariant Theory

Perverse schobers are categorifications of perverse sheaves. We construct a perverse schober on a partial compactification of the stringy Kahler moduli space (SKMS) associated by Halpern-Leistner and


In recent years, sheaf-theoretic constructions have begun to play an increasingly important role in Floer theory in symplectic topology and gauge theory; in many special cases there now exist

Categorification of Legendrian knots

Perverse schober defined by Kapranov--Schechtman is a categorification of the notion of perverse sheaf. In their definition, a key ingredient is certain purity property of perverse sheaves. In this

This note studies perverse sheaves of categories, or schobers, on Riemann surfaces, following ideas of Kapranov and Schechtman (Perverse schobers, arXiv:1411.2772, 2014). For certain wall crossings

New description of perverse sheaves on a disc

There is a connection between the category of perverse sheaves on a disc and different notions related to spherical functors. We introduce a category whose objects are analogous to 4periodic

Derived category of projectivizations and flops

We prove a generalization of Orlov’s projectivization formula for the derived category D coh(P(E )), where E does not need to be a vector bundle; Instead, E is a coherent sheaf which locally admits

Shuffle algebras and perverse sheaves

We relate shuffle algebras, as defined by Nichols, Feigin-Odesskii and Rosso, to perverse sheaves on symmetric products of the complex line (i.e., on the spaces of monic polynomials stratified by

Cluster theory of topological Fukaya categories

We study a class of generalized cluster categories arising from relative Ginzburg algebras of triangulated marked surfaces without punctures. We show that these categories describe 1periodic versions

Parabolic induction and perverse sheaves on W﹨h



How to glue perverse sheaves

The aim of this note [0] is to give a short, self-contained account of the vanishing cycle constructions of perverse sheaves; e.g., for the needs of [1]. It differs somewhat from the alternative

Fukaya Categories as Categorical Morse Homology

The Fukaya category of a Weinstein manifold is an intricate symplectic inva- riant of high interest in mirror symmetry and geometric representation theory. This paper informally sketches how, in

Affine braid group actions on derived categories of Springer resolutions

In this paper we construct and study an action of the affine braid group associated to a semi-simple algebraic group on derived categories of coherent sheaves on various varieties related to the

Tilting exercises

This is a geometry-oriented review of the basic formalism of tilting objects (originally due to Ringel, see [Ri], §5). In the first section we explain that tilting extensions form a natural framework

Braid groups and Kleinian singularities

We establish faithfulness of braid group actions generated by twists along an ADE configuration of 2-spherical objects in a derived category. Our major tool is the Garside structure on braid groups

Triangulated surfaces in triangulated categories

For a triangulated category A with a 2-periodic dg-enhancement and a triangulated oriented marked surface S we introduce a dg-category F(S,A) parametrizing systems of exact triangles in A labelled by

The Theory of Hyperfunctions on Totally Real Subsets of a Complex Manifold with Applications to Extension Problems

Introduction. Suppose K is a compact subset of a Stein manifold. The set K is said to be holomorphically convex if K is homeomorphic to the spectrum of the topological algebra of analytic functions

A vanishing theorem for Holonomic modules with positive characteristic varieties

Let M be a real analytic manifold, X a complexification of M, Ji a holonomic module over the ring $x of microdifferential operators and Char(Jt} its characteristic variety. We prove that if (T%fX,

Constructible sheaves and the Fukaya category

Let $X$ be a compact real analytic manifold, and let $T^*X$ be its cotangent bundle. Let $Sh(X)$ be the triangulated dg category of bounded, constructible complexes of sheaves on $X$. In this paper,
