Title: Spin structure on moduli space of sheaves on CY 3-folds
Date: Fri, Dec 14, 2012, 15:30 - 17:00
Place: Seminar Room A
Abstract: Konstevich and Soibelman 's orientation data is roughly speaking a consistent choice of spin structure on moduli space of sheaves on CY 3-folds. Such spin structure is necessary for defining any refined version of Donaldson-Thomas invariant. I will discuss some recent progress on this subject.
