WebIGCS is the gravitational Chern-Simons action. The Chern-Simons couplings kL,R are now in general com-plex, kL = δ +is , kR = δ −is , (21) with an imaginary part that is related to Newton’s con-stant, s = ℓdS 4GN, and a real part, δ, giving the coefficient of a gravitational Chern-Simons action. Quantum effects WebThis is the famous Chern-Simons term. The coecient k is sometimes called the level of the Chern-Simons term. At first glance, it’s not obvious that the Chern-Simons term is gauge invariant since it depends explicitly on A µ. However, under a gauge transformation, A µ! A µ +@ µ!, we have S CS[A] !

WebJan 3, 1996 · A Chern-Simons action for supergravity in odd-dimensional spacetimes is proposed. For all odd dimensions, the local symmetry group is a non trivial supersymmetric extension of the Poincar\'e group. WebSimons also recalled Chern’s impish sense of humor. In 1972 Simons was a member at the In-stitute for Advanced Study in Princeton and Chern had come for a short visit. This was at the time when the formidable André Weil was on the fac-ulty. At the end of Chern’s stay, Simons was to drive Chern to the train station. Chern had a good deal
