Khovanov homology for links in thickened surfaces and a categorification of the skein algebra multiplication

Date & time

2–3.30pm 9 February 2018


John Dedman Building 27, Room JD1177 (meeting room)

Khovanov homology can be defined for links in thickened surfaces. After reminding us how it works in the thickened annulus (where Khovanov homology naturally carries a $\mathfrak{sl}_2$ action), Hoel Queffelec and Paul Wedrich will explain additional gradings that arise in the general case.
