demi-closed mapping

In this paper, we discuss the relationships between closed maps and closed filters which is closely related with Gabriel topologies.

在Quantale中討論了與Gabriel拓撲密切關聯的閉濾子,給出了閉濾子與閉映射之間的相互確定關系。

To obtain the function and imbedding properties about relative countable tightness spaces,in this paper the question whether the relative countable tightness space can be adversely preserved by a closed map is studied by means of function and imbedding theories.

為了得到相對可數緊度空間的映射及嵌入性質,借助映射方法和緊化理論討論了相對可數緊度空間被閉映射逆保持問題及嵌入緊空間問題,得到了相對可數緊度空間被閉映射逆保持的一個充分條件、局部緊的可數緊度空間可嵌入緊空間的幾個充分條件以及某一類局部緊空間在任意緊化中不具有可數緊度等結果。

Meanwhile,the paper finds out the relationship between prequantale morphism & the operation of a prequantale and obtains that a closed map of prequantales is a necessary & sufficient condition for a prequantale morphism.

找到了Prequantale中態射與蘊涵運算的關系,得到了Prequantale上的一個閉映射是態射的充要條件。

It is also found that the results from the mapping closure model and the counterflow model are very close.

評估了映射封閉模型、對撞流模型、來自均勻湍流PDF輸運方程的模型和一個唯象模型。

Pretopological molecular lattices and open mappings and closed mappings between them;

預拓撲分子格以及它們之間的開映射和閉映射

This paper proved that spaces with σ - hereditarily closure preserving pseudobase be preserving by closed mapping.

證明了具有σ－遺傳閉包保持偽基的空間被閉映射保持。

The spaces with σ-HCP-k networks or with σ-WHCP-k networks have following properties: (1) hereditability; (2) under closed mappings are preserved; (3) locally summation theorem; (4) melization theorem.

具有σ-HCP-k網或具有σ-WHCP-k網的空間有以下性質:(1)遺傳性;(2)在閉映射下被保持;(3)局部和定理;(4)度量化定理。

Deepen the open mapping theorem,define the closed mapping and the weakly closed mapping under untithesis,and also discuss some of their related properties.

深化算子的開映射定理,對偶地定義了算子的閉映射與弱閉映射,并討論了相關的若干性質。

We prove that closed Lindelof mappings with regular domains and images inversely preserve sequential mesocompactness,which improves the same result of Mancuso V J about perfect mappings.

證明了正則空間中閉Lindelof映射逆保持序列式meso緊性,從而改進了Mancuso V J關于正則空間中完備映射逆保持meso緊性這一結果;進一步我們指出定理條件中原象空間的正則性不可被省略而象空間的正則性可以用原象空間的正規性來替代。
