Pure Mathematics Seminar, Title of the talk: Quantum annular Khovanov homology, University of Melbourne, Australia, October 26, 2018

Abstract: In 1999 Khovanov assigned to a knot (or link) a complex whose homotopy type is a link invariant and whose Euler characteristic is the Jones polynomial. This construction is known as a categorification of the Jones polynomial. In the talk I will explain Khovanov’s approach and show that it can be extended to annular links in a way sensible to annular link cobordisms. This is a joint work with K. Putyra and S. Wehrli.
