The strongly star-Hurewicz game nonimplication
The strongly star-Hurewicz game nonimplication
Let be a topological space. The strongly star-Hurewicz property means that for every sequence of open covers of , there are finite sets such that is a -cover of . In the strongly star-Hurewicz game, ONE chooses an open cover in inning , and TWO responds with a finite set ; TWO wins when is a -cover of . The strongly star-Hurewicz game conjecture. The strongly star-Hurewicz property of need not imply that ONE does not have a winning strategy in the strongly star-Hurewicz game played on . The statement concerns the possible failure of the converse to the evident implication from the absence of a winning strategy for ONE to the strongly star-Hurewicz property; the source provides no resolution or example.
