Abstract
We study properties of the infimal topology τ inf which is the infimum of the family of all topologies of uniform convergence defined on the set C(X, Y) of continuous maps into a metrizable space Y. One of the main results of the research consists in obtaining necessary and sufficient condition for the topology τ inf to have the Fréchet–Urysohn property. We also establish necessary and sufficient conditions for coincidence of the topology τinf and a topology of uniform convergence τ μ (“attaining” the infimum). We prove that for this coincidence it is sufficient for the topology τ inf to satisfy the first axiom of countability.
