The Topological G / G WZW Model in theGeneralized Momentum
We consider the topological gauged WZW model in the generalized momentum representation. The chiral eld g is interpreted as a counterpart of the electric eld E of conventional gauge theories. The gauge dependence of wave functionals (g) is governed by a new gauge cocycle GWZW. We evaluate this cocycle explicitly using the machinery of Poisson-models. In this approach the GWZW model is reformula...
متن کاملTopological G/G WZW model in the generalized momentum representation.
We consider the topological gauged WZW model in the generalized momentum representation. The chiral field g is interpreted as a counterpart of the electric field E of conventional gauge theories. The gauge dependence of wave functionals Ψ(g) is governed by a new gauge cocycle φ GW ZW. We evaluate this cocycle explicitly using the machinery of Poisson σ-models. In this approach the GWZW model is...
متن کاملG-Frames, g-orthonormal bases and g-Riesz bases
G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection between g-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a bounded operator.
متن کاملPointed Admissible G-covers and G-equivariant Cohomological Field Theories
For any finite group G we define the moduli space of pointed admissible G-covers and the concept of a G-equivariant cohomological field theory (G-CohFT), which, when G is the trivial group, reduce to the moduli space of stable curves and a cohomological field theory (CohFT), respectively. We prove that taking the “quotient” by G reduces a G-CohFT to a CohFT. We also prove that a G-CohFT contain...
