Venue:W11, Ning Zhai


This course is to give an introduction to categorification from topological and algebraic point of view. We will discuss Khovanov homology as a categorification of the Jones polynomial. On the algebraic side, we will discuss categorified quantum group theory, due to Khovanov-Lauda, Rouquier and Webster.


A little homological algebra will be helpful but not necessary.
