I want to read about Wittens work, on Cherns-Simons theory, and relations to knots and jones polynomials. I am extremely motivated to read his paper: Quantum Field Theory and Jones polynomial.
What are the prerequisites in topology, geometry and QFT needed to understand this paper? I have good grasp of basic point-set topology concepts, and have read about manifolds(Nakahara). In QFT, I have just started QED. What do I need to study from each of these? As per my knowledge, I need some knot theory and cohomology(?), and quantum yang-mills theory. Is this correct? Also please provide references.
