[geometry-ml:02550] MS seminar at Kavli IPMU -- Timothy Logvinenko (Cardiff U) -- Jan 19

[Todor Milanov]

Dear all,

I would like to announce the following Mathematics and String theory seminar at IPMU

Speaker: Timothy Logvinenko	(Cardiff U)
Date: Tue, Jan 19, 2016, 15:30 - 17:00
Place: Kavli IPMU, Seminar Room B

Title: “P-functors”

Abstract:

"P^n objects are a class of objects in derived categories of algebraic varieties first studied by Huybrechts and Thomas. They were shown to give rise to derived autoequivalences in a similar fashion to Seidel-Thomas spherical objects. It was also shown that they could sometimes be produced out of spherical objects by taking a hyperplane section of the ambient variety.
 
In this talk, we’ll first recall the basics on spherical and P^n objects, and then explain how to generalise the latter to
the notion of P-functors between (enhanced) triangulated categories. We'll also discuss a closely related notion of a non-commutative line bundle over such category. This is based on work in progress with Rina Anno and Ciaran Meachan.”
