On proximities generated by countable families of entourages Svetlozar Ivanov, Jan Pelant, S. Nedev (2004) Commentationes Mathematicae Universitatis Carolinae It is shown that any proximity that is generated by a countable family of entourages is sequential. Metrization theorems for proximities are derived.
