摘要
本文证明了仿近似紧(紧式仿近似紧,弱仿近似紧)空间在一定条件下被几乎连续闭几乎开映射逆保持,推广了〔1〕的主要结果。
In this paper, we prove that near paracompact(near mesocompact, near metacompact)spaces are inversely preserved by the almost continuous closed almost open mapping under some conditions and the results of this paper have popularized the Suyatu's result in (1).
