1) base-mesocompact mapping
基中紧映射
1.
It is investigated that base-metacompactness and base-mesocompactness are inversely preserved under perfect mapping,closed Lindelf mapping,base-paracompact mapping,base-metacompact mapping and base-mesocompact mapping.
引入了基亚(中)紧空间和基亚(中)紧映射的概念,并研究了完备映射、闭Lindel f映射、基仿紧映射、基亚紧映射、基中紧映射对基亚紧性和基中紧性的保持问题。
2) countable base-mesocompact mapping
基-可数中紧映射
1.
The notion of countable base-mesocompact mapping is introduced and the following results are mainly proved:(i) Let f ∶X→Y be countable base-mesocompact mapping.
引入了基-可数中紧映射,并且获得了如下主要结果:(i)设X,Y为T2空间,ω(X)≥ω(Y),f∶X→Y是基-可数中紧映射,如果Y是正则的基-可数中紧空间,那么X是基-可数中紧空间。
3) mesocompact map
中紧映射
1.
In this paper,after we introduce the concept of a mesocompact map,we study and proof a lemma,then proof a equivalent chracterization of severel concepts in the condition of closed map.
引入了中紧映射后,先研究并证明了一个引理,再证明了几个概念在闭映射的条件下的等价刻画,最后不仅利用定向开覆盖刻划了中紧映射,还利用闭包保持闭加细,紧式星形加细,紧式w-加细和紧式星形Fk-加细等进一步刻划了中紧映射,拓展了拓扑空间范畴到拓扑空间范畴的映射。
4) base-paracompact mapping
基-仿紧映射
5) basemetacompact mapping
