摘要
In this article we investigate which compact spaces remain compact under countably closed forcing. We prove that, assuming the Continuum Hypothesis, the natural generalizations to omega(1)-sequences of the selection principle and topological game versions of the Rothberger property are not equivalent, even for compact spaces. We also show that Tall and Usuba's "N-1-Borel Conjecture" is equiconsistent with the existence of an inaccessible cardinal. (C) 2013 Elsevier B.V. All rights reserved.
