•  Wenzhao Chen, MSU
•  Casson's invariant for oriented integer homology spheres
•  03/18/2019
•  1:40 PM - 3:00 PM
•  C304 Wells Hall

This talk is an exposition of Casson's invariant: we will cover the definition of Casson's invariant in terms of Heegaard decomposition and representation spaces, and show how it can be computed (and defined) in terms of the Alexander polynomial of knots.
