Sheaves as Three-manifold Invariants
Chien-Hsun Wang (NCTS)

Abstract:

Given a Heegaard splitting of a closed, connected, oriented three-manifold, Abouzaid and Manolescu defined a perverse sheave on the character variety of the fundamental group as an invariant for the three-manifold. They showed that it is invariant under stabilization and independent of a sequence of moves.
