Crossingless sheaves and their classes in equivariant K-theory

Algebraic Geometry 2022-12-29 v1

Abstract

We introduce crossingless sheaves in certain equivariant derived categories which are analogous to the Bezrukavnikov-Mirkovic exotic sheaves for two-block nilpotents. We calculate the classes of crossingless sheaves in equivariant K-theory of Cautis-Kamnitzer varieties.
