Abstract:
At the first discussion, we have introduced the general framework of TQFT. This time we will discuss the properties of Chern-Simons theory in detail, which is a very important kind of Schwarz TQFT that related to many branches of physics and mathematics, e.g. knot theory, string theory, conformal field theory, quantum gravity and so on. And we will continue to discuss the some basics on knot theory and the relation between the knot invariants and Chern-Simons theory.
