Chern theory
WebJul 28, 1992 · Chern-Simons Gauge Theory As A String Theory Edward Witten Certain two dimensional topological field theories can be interpreted as string theory backgrounds in which the usual decoupling of ghosts and matter does not hold. Like ordinary string models, these can sometimes be given space-time interpretations.

Web3 string theory is the modular-invariant partition function of the dual CFT on the boundary. This is a puzzle because AdS 3 string theory formally reduces to pure Chern–Simons theory at long distances. We study this puzzle in the context of mas-sive Chern–Simons theory. We show that the puzzle is resolved in this context by the WebChern{Simons theory with gauge supergroup Rozansky{Witten theory of a holomorphic symplectic manifold (intuition: fermionic counterpart of compact Chern{Simons theory) …
The Chern–Simons theory is a 3-dimensional topological quantum field theory of Schwarz type developed by Edward Witten. It was discovered first by mathematical physicist Albert Schwarz. It is named after mathematicians Shiing-Shen Chern and James Harris Simons, who introduced the Chern–Simons 3-form. … See more Mathematical origin In the 1940s S. S. Chern and A.

WebChern-Simons theory is a 3-dimensional topological field theory. The word “topological” means the theory does not depend on the metric of the space, but depends on the topology of the space. Yang-Mills theory is not a topological theory, it is metric dependent. WebChern-Simons theory is supposed to be some kind of TQFT. But what kind of TQFT exactly? When mathematicians say that it is a TQFT, does this mean that it's a certain kind of functor from a certain bordism category to a certain target category? If so, what kind of functor is it? What kind of bordism category is it?
