Small loop spaces and covering theory of non-homotopically Hausdorff spaces
Ali Pakdaman, Hamid Torabi, Behrooz Mashayekhy
In this paper we devote to spaces that are not homotopically hausdorff and study their covering spaces. We introduce the notion of small covering and prove that every small coverin…
