Popis: The purpose of this paper is to determine what natural functors T : A → X T:{\mathbf {A}} \to {\mathbf {X}} are ( E , M ) (\mathcal {E},\mathfrak {M}) -topological, where A {\mathbf {A}} is a subcategory of the category of proximity or uniform spaces and X {\mathbf {X}} is an ( E , M ) (\mathcal {E},\mathfrak {M}) -category. We give necessary and sufficient conditions under which a point separating family of continuous functions can be nicely lifted to a proximally continuous family. Proximities having a finest compatible uniform structure are characterized.
