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. |
