映射正规性的函数方法

Functional approach to the normality of mappings

Mikhail Yourievich Liseev

AI总结:

本文通过 $f$-连续函数及其函数族研究映射的正规性,证明映射版 Urysohn 引理与 Brouwer-Tietze-Urysohn 扩张定理,并引入完全正规性概念。

摘要:

本文发展了一种使用(映射上的)$f$-连续函数及其函数族的技术。文中给出了映射版 Urysohn 引理的证明,并证明了映射版 Brouwer-Tietze-Urysohn 扩张定理的一个变体。文章给出了映射正规性性质的若干刻画,并引入了映射的完全正规性概念;在该方法中,这似乎是最优的。

英文摘要:

In the article a technique of the usage of $f$-continuous functions (on mappings) and their families is developed. A proof of the Urysohn's Lemma for mappings is presented and a variant of the Brouwer-Tietze-Urysohn Extension Theorem for mappings is proven. Characterizations of the normality properties of mappings are given and the notion of a perfect normality of a mapping is introduced. It seems to be the most optimal in this approach.
