Title: Quasiphantom categories in derived categories of surfaces isogenous to a higher product
Date: Tue, Dec 08, 2015, 15:30 - 17:00
Place: Seminar Room B
Abstract: I will present and discuss exceptional collections of maximal length 4 on surfaces isogenous to a higher product with p_g=q=0. Quasiphantom categories are obtained as orthogonal complements of these exceptional collections. Part of this is joint work with Timofey Shabalin, Hyun Kyu Kim, Yun-Hwan Kim.
