摘要
该文主要证明了如下结果:引理在ω<ω。上存在一个滤子满足:对于每个次meso紧空间X和X的每个开覆盖,存在的开加细序列使得对于任何紧子集.有.定理设X是正则meso紧(次meso紧)空间,Y是meso紧(次meso紧)空间,如果PlayerI在G(DC,X)中有必胜策略。
The following results are proved. Lemma the is a filter on <ω satisfying: For every submesocmpact space X and every open cover of X, there is a sequence of open refinernents of such that for every K∈(X), Theorem Let X be a regular submesocmpact space and Y a submesocompact space. If Player I has a winning straegy in G(DC, X), then X×Y is mesocompact(submesocompact).
