Star versions of Menger basis covering property and Menger measure zero spaces

Authors: Manoj Bhardwaj

Abstract:

In this paper, we consider the star version of Menger basis covering property introduced by Menger in 1924. The author obtained relationship between star-selection principles and star versions of Menger basis covering property for metrizable spaces. We also consider star versions of Menger measure zero spaces and characterize these new spaces by star-selection principle related to star-Menger spaces. In this manner, we obtained relationships of star-Menger property with other existing properties in literature.

Keywords: Menger space, star-Menger, $ω$-star-Menger basis property, $ω$-star-Menger measure zero, groupable-star-Menger measure zero, star-selection principles
