WebJan 15, 2009 · Chern-Simons theory as initially conceived from the path integral is a 2-3 theory. Reshetikhin and Turaev [RT], [Tu] give a rigorous mathematical construction when the gauge group is simple and simply connected; it utilizes a suitable category of representations of a related quantum group. Hence they construct a 1-2-3 theory; WebThere are several different relations between Chern-Simons/WZW models, and there are several way to show these.

WebChern-Weil Theorem For any smooth section A of the bundle End(E), the ﬁberwise trace of A forms a smooth function on M. We denote this function by tr[A].

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? mypay cac certificate

WebOct 26, 2024 · To me, the logic to adopt (Maxwell-) Chern-Simons theory as an effective theory is pretty bottom up (says, Wen's book): We can write down a current with fractional Hall conductivity, from which we can introduce the statistical gauge fields as auxiliary fields for the effective action and it turns out to be the Chern-Simons theory. Physics Nobel Prize winner (and former student) C. N. Yang has said that Chern is on par with Euclid, Gauss, Riemann, Cartan.
