We study the «topological gauged WZW model associated with SU(2)/U(1)», which is defined as the twisted version of the corresponding supersymmetric gauged WZW model. It is shown that this model is equivalent to a topological conformal field theory characterized by two independent topological conformal algebras, one of which is the «twisted Kazama-Suzuki type» and the other is the «twisted Coulomb gas type». We further show that our formalism of this gauged WZW model naturally reduces to the well-known formulations of two-dimensional gravity coupled with conformal matter, one of the gauge choices leads to Li's theory, and the alternative choices lead to the KPZ theory or the DDK (Liouville) theory.
