| 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. |
