Corks for exotic diffeomorphisms

June 4, 2024 @ 2:00 pm - 3:00 pm

Speaker: Slava Krushkal, University of Virginia

Title: Corks for exotic diffeomorphisms

Abstract: Exotic smooth structures on simply-connected 4-manifolds are known to be related by cork twists: cutting out and re-gluing certain smooth contractible submanifolds. Work in progress, joint with A. Mukherjee, M. Powell, and T. Warren, provides a localization result for exotic diffeomorphisms of 4-manifolds. I will also discuss applications to known examples of exotic diffeomorphisms.
