Geometry and Topology Seminar: Marithania Silvero Casanova, Universidad de Sevilla, Positivity, fiberedness and link homology

September 29, 2023 | 12:50 pm - 1:50 pm EDT

Khovanov homology is a link invariant which categorifies Jones polynomial. In this talk we present several results concerning Khovanov homology of fibered positive links; in particular, we extend the result by Stosic stating that braid positive links have vanishing Khovanov homology in homological grading 1. We also explore Khovanov homology of certain cable links and present computational data suggesting that the above result can be extended to L-space knots. This is joint work with M. Kegel, N. Manikandan and L. Mousseau.
