On new star-selection principles in topology
Topology and Its Applications, 2020In this paper the authors study some new selection principles using the star operator which was introduced by \textit{P. Bal} and \textit{S. Bhowmik} [``Some new star-selection principles in topology'', Filomat 31, No. 13, 4041--4050 (2017)]. They ask the following question: Is there a space \(X\) which does not have the property \(^{\star}U_{1 ...

Star-Selection Principle: Another New Direction
Journal of the Indian Mathematical Society, 2017Generally selection principles deal with two collections of families of subsets. In this paper we have introduce some new star-selection principles termed as SS*<sub>C,1</sub>(<em>A, B</em>) and SS*<sub>C,fin</sub>(<em>A, B</em>) which deal with three collections of subsets or families of subsets of a set.

Star selection principles: a survey
2015Summary: We review selected results obtained in the last fifteen years on star selection principles in topology, an important subfield of the field of selection principles theory. The results which we discuss concern also uniform structures and, in particular, topological groups and their generalizations.

In this paper, using families of closed sets and a few modifications to the finite intersection features, we characterize the Rothberger Space and the Star-Rothberger Space. We also provide the selection principles that, in a reversed approach, can represent the Rothberger spaces and the star-Rothberger Spaces.
