Event description: 

Recently, Francis Bonahon, Helen Wong and Tian Yang constructed a quantum invariant for surface diffeomorphism using representation theory of Kauffman Bracket Skein Algebra. They proposed a conjecture that relates this invariant with the volume of mapping torus coming from the diffeomorphism. We will talk about this construction, some explicit computation techniques and recent results.
