摘要
主要获得两个σ－ｍｅｓｏ紧空间的乘积是σ－ｍｅｓｏ紧空间的两个定理．
In this paper, we obtained the following two theorems on σ- mesocompact spaces. If X is a σ-mesocompact P-space and Y is a σ-mesocompact strong ∑ - space, the X × Y is a σ- mesocompact space,or if { Xi: i∈N} are countable σ-mesocompact strong ∑ -spaces,the i∈NпXi is a σ- mesocompact ∑-space
