Abstract:
Perverse schobers are a recent notion introduced by Kapranov and Schechtman. It is a categorification of perverse sheaves on a stratified topological space. In this talk, I will introduce perverse schobers, describe several known examples, and then talk about a joint work in progress with Alexei Bondal where we study perverse sheaves and perverse schobers on an orbifold disc.
