摘要 利用拓扑博弈G(DC,X)的理论,推广了关于meso-紧空间有限乘积性质并得到如下结果:(1)如果i∈ω,Yi是正则DC-like的meso-紧空间,则iωYi是meso-紧的;(2)如果i∈ω,Yi是正则C-散射meso-紧的P-空间,则i∈ωYi是meso-紧的. Making use of the theories of topological game G(DC,X),we extend the finite products of the mesocompact space.And it is proved that:(1) The product Πi∈ω Yi is mesocompact if Yi is a regular DC-like mesocompact space for each Πi ∈ ω.(2) The produc i∈ω Yi,if Yi is a regular C-scattered mesocompact P-space for each i ∈ ω.
