Topologically inseparable functions I: Finitary case
Semigroup Forum, Vol. 66, N°1, 18-42, 2003
Given a finite set A and a distinguished function f: A → A, we study the set of all functions g: A → A that are continuous for all topologies for which f is continuous. The main result is a characterization of the functions f such that this set is trivial, that is, contains only the constant functions and the iterates of f.
