Abstract

This article is a continuation of our investigations in the function space C(X)C(X) with respect to the topology τBs\tau^s_\mathfrak{B} of strong uniform convergence on B\mathfrak{B} in line of (Chandra et al. 2020 \cite{dcpdsd} and Das et al. 2022 \cite{pddcsd-3}) using the idea of strong uniform convergence (Beer and Levi, 2009 \cite{bl}) on a bornology. First we focus on the notion of tightness property of (C(X),τBs)(C(X),\tau^s_\mathfrak{B}) and some of its variations such as supertightness, Id-fan tightness and TT-tightness. Certain situations are discussed when C(X)C(X) is a {\rm k}-space with respect to the topology τBs\tau^s_\mathfrak{B}. Next the notions of strong B\mathfrak{B}-open game and γBs\gamma_{\mathfrak{B}^s}-open game on XX are introduced and some of its consequences are investigated. Finally, we consider discretely selective property and related games. On (C(X),τBs)(C(X),\tau^s_\mathfrak{B}) several interactions between topological games related to discretely selective property, the Gruenhage game on (C(X),τBs)(C(X),\tau^s_\mathfrak{B}) and certain games on XX are presented.
