On Minimal Door, Minimal Anti-compact and Minimal

Abstract

We prove that a topological space (X, τ) is a minimal door space if and only if either (i) it is a hyperconnected door space or (ii) τ is an excluded point topology; our proof makes use of Steiner’s characterisation of door spaces in terms of ultraspaces. We show that minimal door spaces are precisely the connected door spaces and that door… (More)
