Countably mesocompact spaces and function insertion
Abstract
A topological space X is called countably mesocompact if for every
countably open cover U of X, there exists an open refinement V of U
such that {V ∈ V : V ∩K 6= ∅} is finite for every compact set K in X. In
this paper, we investigate relations between insertion of semi-continuous
functions and a kind of spaces with countable mesocompactness , and
give some characterizations of countably mesocompact spaces, k-perfect
spaces and k-MCM spaces.
