Title: Invariants of annular links, cobordisms and transverse links from combinatorial link Floer complex
Speaker: Apratim Chakraborty (ISI, Bangalore)
Date: 04 November 2019
Time: 4:15 pm
Venue: LH-2, Mathematics Department

We will define an invariant for annular links using the combinatorial link Floer complex that gives genus bounds for annular cobordisms. The celebrated slice-Bennequin inequality relates slice genus of a knot with its contact geometric invariants. We investigate similar relations in our context. In particular, we will define an invariant of transverse knots that refines the transverse invariant $\theta$ in knot Floer homology.
