Louis H Kauffman
Introduction to the Hennings-Kauffman-Radford Invariant
Abstract: This will be the first of two talks about the Hennings-Kauffman-Radford (HKR) invariant and the Kuperberg invariant of three-manifolds. These talks will precede the Februrary 8 talk by Shawn Cui, who will prove a conjectured relationship between the two invariants. The HKR invariant is defined via Hopf algebras using surgery on framed links. The Kuperberg invariant is defined via Hopf algebras using a Heegaard decomposition of the three manifold.
