Geometry and Physics Seminar

Quantum group and its application to knot polynomial was the theme of Witten-Reshtikhin-Turaev theory.  The categorification of quantum group and application to knot homology has been discovered and developed by Khovanov-Lauda, Rouquier, and Webster, in the form of KLRW algebra. With Mina Aganagic and collaborators, we developed a new approach using Fukaya category and relate to KLRW algebra. The geometric origin allows us to give a geometric construction for the categorified coproduct. The talk is based on past work and work in progress with Mina Aganagic, Vivek Shende, Elise LePage, Ivan Danilenko and Yixuan Li. 

Please note the change in time from the seminar's usual scheduled time.
