课程安排：

1.2022年8月11日 14:00 - 16:00，The Jones polynomial and 3D TQFT.

We give an introduction to the Jones polynomial from algebraic and topological perspectives. We also explain the idea of a generalization to 3-manifold invariants, Witten-Reshetikhin-Turaev invariant.

2. 2022年8月13日 14:00 - 16:00，Khovanov homology, a categorification of the Jones polynomial.

We introduce a celebrated example of categorification, Khovanov homology, as a categorification of the Jones polynomial. As an application, we explain Rasmussen's combinatorial proof of the Milnor conjecture.

3.2022年8月15日 14:00 - 16:00， Soergel bimodules and Khovanov-Rozansky homology

We introduce a generalization of Khovanov homology as a categorification of the HOMFLY-PT polynomial. It is closely related to Hecke algebras and its categorification.

4. 2022年8月17日 14:00 - 16:00，Quantum groups and categorification

We discuss the representation theory of quantum groups behind the link invariants. We also explain the categorified quantum group based on the notion of canonical bases.
