Instanton and Spectral Flow in Topological Conformal Field Theories

Abstract

A class of two-dimensional topological conformal field theories (TCFTs) is studied within the framework of gauged WZW models in order to obtain some insights on the global geometrical nature of TCFTs. The BRST quantizations of topological G/H gauged WZW models ( the twisted versions of supersymmetric gauged WZW models ) are given under fixed back-ground… (More)
