On strategies for selection games related to countable dimension

General Topology 2023-01-13 v1

Abstract

Two selection games from the literature, Gc(O,O)G_c(\mathcal O,\mathcal O) and G1(Ozd,O)G_1(\mathcal O_{zd},\mathcal O), are known to characterize countable dimension among certain spaces. This paper studies their perfect- and limited-information strategies, and investigates issues related to non-equivalent characterizations of zero-dimensionality for spaces that are not both separable and metrizable. To relate results on zero-dimensional and finite-dimensional spaces, a generalization of Telg\'{a}rsky's proof that the point-open and finite-open games are equivalent is demonstrated.
