Original Abstract

We study a number of categorical quasi-uniform structures induced by functors. We depart from a category C with a proper (E,M)-factorization system, then define the continuity of a C-morphism with respect to two syntopogenous structures (in particular with respect to two quasi-uniformities) on C and use it to describe the quasi-uniformities induced by pointed and copointed endofunctors of C. In particular, we demonstrate that every quasi-uniformity on a reective subcategory of C can be lifted to a coarsest quasi-uniformity on C for which every reection morphism is continuous.

Keywords

Closure operator, Syntopogenous structure, Quasi-uniform structure, (Co)pointed endofunctor, and Adjoint functor.
