1) κ-closure preserving
κ闭包保持
2) closure-preserving
闭包保持
1.
In this paper metacompact maps and paracompact maps are characerized in terms of locally finite,point-finite semi-open refinements of open covers,and the existence of closure-preserving closed refinements,interior-preserving open star-refinements of interior-preserving directed open covers.
主要利用开覆盖的局部有限,点有限半开加细及内核保持定向开覆盖的闭包保持闭加细,内核保持开星加细等进一步刻划仿紧映射和亚紧映射。
3) σ-closure preserved
σ-闭包保持
5) α_closure_preserving family
α-闭包保持族
6) α-hereditarily closure-preserving
σ-遗传闭包保持
