»On the geometry of contractions of the Moduli Space of sheaves of a K3 surface«

Abstract:
I will describe how recent advances have made possible to study the birational geometry of hyperkaehler varieties of K3-type using the machinery of wall-crossing and stability conditions on derived categories as developed by Tom Bridgeland. In particular Bayer and Macrì classify birational transformations of the moduli space M of sheaves of a K3 surface X in temrs of wall-crossing in the space of Bridgeland stability conditions Stab(X). I will explain how it is possible to refine their analysis to give a precise description of the geometry of the exceptional locus of any birational contractions of M.
