Relative versions of some star-selection principles

Abstract

We introduce some relative versions of star selection principles rst considered in [5], [11]. Some of the work extends results from [4], [5] and gives some examples.

Weakly strongly star-Menger spaces

“…In this section we study subspaces of a WSSM space and also show that product of two WSSM spaces need not be WSSM. For some relative version of star selection principles see ( [4,5,19]). Proof.…”
