概要: 

I will begin by reviewing the geometry of a cyclic cover branched in a divisor. I will then explain how it gives the first ever example of a non-split P^n-functor. If there is time, I will also explain the connection with the notion of a perverse schober introduced by Kapranov and Schechtmann. This is a joint work with Rina Anno (Kansas).
