Definable separability and second-countability in o-minimal structures

We show that separability and second-countability are first-order properties of topological spaces definable in o-minimal expansions of $(\mathbb R, \lt )$. We do so by introducing first-order characterizations – definable separability and definable secon

Abstract

We show that separability and second-countability are first-order properties of topological spaces definable in o-minimal expansions of $(\mathbb R, \lt )$. We do so by introducing first-order characterizations – definable separability and definable secon
