Annular Khovanov-Lee theory and representation theory

Presented by: 
Eli Grigsby Boston College
Thursday 19th January 2017 - 11:30 to 12:30
INI Seminar Room 1
After reminding you of the main properties of Khovanov-Lee theory underlying Rasmussen's proof of the topological Milnor conjecture, we will discuss the representation theory underlying an annular version of Khovanov-Lee theory (j. work with T. Licata and S. Wehrli), focusing on how geometric features of the braid interact with representation-theoretic features of the Khovanov-Lee complex.
