Title:  Enumerative Geometry of Quot schemes on 3-folds

Abstract:
We discuss the existence of a virtual fundamental class on Quot schemes
of locally free sheaves on complex 3-folds. We compute Behrend’s virtual Euler characteristic of these Quot schemes, 
which in some cases gives rise to new examples of (higher rank) Donaldson-Thomas invariants. 
If time permits, we will sketch the parallel theory of motivic invariants.
