Abstract:
In my talk I shall explain how the theory of twisted sheaves on elliptic fibrations provides the key ingredient to solving a puzzle posed in 1992 by Vafa and Witten: a physical theory exhibited by them that is smooth (in the physics sense), but appears to not be compactified on any smooth space.Date: Tuesday, March 16, 2004
