Frechet space

A theorem on Frechet space structure

关于Frechet空间结构的一个定理

Especially , by means of the first degree stop-loss order , we show that the mutually exclusive risk portfolio in a Frechet space leads to the smallest stop-loss reinsurance premium .

特别地，以一阶停止损失序作为过渡，说明了在Fréchet空间中相斥风险组合的停止损失再保费为最小。

Finally , the Frechet space and Frechet bounds are summarily introduced and a detailed discussion of the mutually exclusive risks , a kind of extreme correlated risks , is carried out .

最后，本文介绍了Fréchet空间与Fréchet界的概念，并较为深入地讨论了一类极端的相依性风险，即相斥风险。

This article discusses the Frechet space structure . The result shows that closed set K in Frechet space X is compact if and only if there exist x_n ∈ X such that x_n → 0 ( n →∞) and K (?)

本文讨论了Frechct空间的结构，证明了：Frechet空间X中的闭集K是紧的当且仅当存在xn∈x，使得xn→0（n→∞）。并且K（？）

T_ ( 3 ( 1 / 2 )) & form frechet ( V ) space

T（3（1/2））&型邻域空间

By thoroughly discussing some specific problems in analysis which are related to the point set topology before Frechet introducing the metric space , the paper studies the analysis origin of point set topology during its invention .

对弗雷歇在引入度量空间的理论之前，和点集拓扑学理论发展相关的一些分析学中的具体问题做了深入细致的研究，即考察了点集拓扑学诞生过程中的分析学渊源。

The approximation problems of isometric operators between finite dimensional Frechet spaces , or between infinite dimensional Frechet space ( s ) are affirmative .

无穷维Frechet空间（s）空间上的等距逼近问题也是肯定的。
