关于meso紧和次meso紧的σ-积

σ-Products on Submesocompact and Mesocompact Spactes

主要获得了如下结果 :设X =σ{Xα:α∈A} ,如果X的每个有限子积是meso紧 (次meso紧 )的且X正规 ,则X是meso紧 (次meso紧 )

This paper mainly obtains the following results: Let X=σ{X-α: α∈Q}. If every finite subproduct of X is mesocompact(submesocompact) and X is normal, then X is mesocompact(submesocompact).
