In this study, we study new applications of Polish group and new relations with several certain classes of topological spaces such as metrizable space, seprable space, Nagata space and M3-space. If G is a top-gp and (X, dθ) is a separable com-θ-metric space then G is Polish group. If G is a top-gp and X a top-space and each point in X has a neighbourhood which is homeomorphic to an open subset of Rn then G is a Polish group. ER -
