Organizer： Hao Wang (Tsinghua)

Speaker：Hao Wang

Title:

Introduction to topological quantum field theory.

Description:

The knot theory is an interesting and active research area in mathematics, which has a deep relation with the topological quantum field theories (TQFT). We will discuss topological quantum field theory from both physics and mathematical perspectives and specifically, introduce one of the most important kinds of TQFT, the Chern-Simons theory that is deeply related to the knot invariant which was discovered by Edward Witten in the famous paper “Quantum Field Theory and Jones Polynomial” published.

A lower bound for the genus of a knot using the Links-Gould invariant
AbstractFor a long time, the Alexander polynomial was the only easily computable link invariant to be known. But in 1984, Jones discovered his well known polynomial link invariant, and that gave birth to the vast theory of quantum link invariants. However, unlike for the Alexander invariant, it is in general hard to deduce precise topological properties on a knot or link from the value quantum ...
