摘要
引入基-κ-亚紧空间的概念,研究了基-κ-亚紧空间与其子空间的关系,基-κ-亚紧空间与κ-亚紧空间的关系,基-κ-亚紧空间与紧空间的乘积,既开又闭的有限到一映射保持基-κ-亚紧性.
The notion of basemetacompact space is introduced and the following is studied: the relation between a base-κ-metacompact space and its subsest, the relation between base-κ-metacompact spaces and κ-metacompact spaces, the product of a base-κ-metacompact space and a compact space, and that open-closed finite-to-1 map preserves base-κ-metacompactness.
