On Selectively Star-Lindelof Properties
Prasenjit Bal, Subrata Bhowmik, David B. Gauld · Journal of the Indian Mathematical Society · 2018
In this paper a new covering notion, called M-star-Lindelof, is introduced and studied. This notion of covering arises from the selection hypothesis SS*D,fin(D, D). The stronger form SS*D,1(D, D) of the selection hypothesis SS*D,fin(D, D) will also be discussed. We then consider weaker versions of these properties involving iterations of the star operator.
