Quantum Invariants and Quantum Representations

Speaker:Yang Tian
Schedule: Tue & Thu 13:30-15:05,2019-7-23 ~ 8-21
Venue:Conference Room 1, Jin Chun Yuan West Building

Description

This is an introduction to quantum Topology.
In the first half of this series of lectures, I will introduce the colored Jones polynomials of knots and links, the Reshetikin-Tureav invariants of 3-manifolds and the Volume Conjecture that relate those invariants with hyperbolic geometry.
The second half of the series will focus on the Reshetikhin-Turaev representations of the mapping class group of surfaces. The AMU Conjecture claiming that those representations respect the Nielsen-Thurston classification will be introduced.
I will use the skein theoretical approach to the theory which requires the minimum prerequisites.

Prerequisite

Basic abstract algebra, basic knowledge of smooth manifolds, fundamental group and homology.
