Relationships between some selection principles and star selection principles

Abstract

Motivated by the definition of classical star selection principles, Cruz-Castillo, Ramírez-Páramo and Tenorio defined some selection principles and posed several questions about relationships between these notions and some of the classical star selection principles. The main goal of this paper is to answer the questions posed by these authors. In addition, we show that some of these defined selection principles are equivalent by taking collections of complements; also, some other results are provided involving collections of refinements.
