On star-C-menger spaces

Yan-Kui Song, Zheng Yin

Abstract


A space X is star-C-Menger if for each sequence (Un : n ∈ N) of open covers of X there exists a sequence (Ksub>n : n ∈ N) of countably compact subsets of X such that {St(Kn; Un) : n ∈ N} is an open cover of X. In this paper, we investigate the relationship between star-C-Menger spaces and related spaces, and study topological properties of star-<C-Menger spaces.

Keywords: Selection principles, star-Menger, star-K-Menger, star-C-Menger, star-L-Menger, starcompact, star-Lindelof, starcompact, star-L-Lindelof.
