Definable one dimensional topologies in o-minimal structures

Submission date: 21 July 2018

Abstract:

We consider definable topological spaces of dimension one in o-minimal structures, and state several equivalent conditions for when such a topological space (X,τ) is definably homeomorphic to an affine definable space (namely, a definable subset of M^{n} with the induced subspace topology). One of the main results says that it is sufficient for X to be regular and decompose into finitely many definably connected components.
