Abstract

We study selection principles related to bornological covers using the notion of ideals. We consider ideals I\mathcal I and J\mathcal J on ω\omega and standard ideal orderings KB,KKB, K. Relations between cardinality of a base of a bornology with certain selection principles related to bornological covers are established using cardinal invariants such as modified pseudointersection number, the unbounding number and slaloms numbers. When IJ\mathcal I \leq_\square \mathcal J for ideals I,J\mathcal I, \mathcal J and {1-1,KB,K}\square\in \{1\text{-}1,KB,K\}, implications among various selection principles related to bornological covers are established. Under the assumption that ideal I\mathcal I has a pseudounion we show equivalences among certain selection principles related to bornological covers. Finally, the I-Bs\mathcal I\text{-}\mathfrak B^s-Hurewicz property of XX is investigated. We prove that I-Bs\mathcal I\text{-}\mathfrak B^s-Hurewicz property of XX coincides with the Bs\mathfrak B^s-Hurewicz property of XX if I\mathcal I has a pseudounion. Implications or equivalences among selection principles, games and I-Bs\mathcal I\text{-}\mathfrak B^s-Hurewicz property which are obtained from our investigations are described in diagrams.
