Related reflections to the axioms of separation in semigroups with topologies and some applications
arXiv:1808.09567
Abstract
In this paper we study the reflections of the category of topological and semitopological semigroups on the category of the class of topological spaces satisfying separation axioms , , , and regular and we apply its properties for to find conditions under which a topological semigroup has the Souslin property.
