    Polish Space

    Description

    A Polish space is a completely metrizable topological vector space X = (X, τ) which is separable relative to τ. In particular, a topological space X is Polish if and only if it is homeomorphic to a complete metric space M = (M, d) where M has a countable subset which is dense relative to d.
