Abstract

A topological space XX is defined to have an ωω\omega^\omega-base if at each point xXx\in X the space XX has a neighborhood base (Uα[x])αωω(U_\alpha[x])_{\alpha\in\omega^\omega} such that Uβ[x]Uα[x]U_\beta[x]\subset U_\alpha[x] for all αβ\alpha\le\beta in ωω\omega^\omega. We characterize topological and uniform spaces whose free (locally convex) topological vector spaces or free (Abelian or Boolean) topological groups have ωω\omega^\omega-bases.
