关于开良滤空间

On open well-filtered spaces

Chong Shen, Xiaoyong Xi, Xiaoquan Xu, Dongsheng Zhao

AI总结:

本文引入开良滤空间,证明良滤空间皆为开良滤空间,且核紧的开良滤空间是 sober 的,从而以更直接的方法肯定回答了贾和容的开放问题。

摘要:

我们引入并研究了一类新的$T_0$空间,称为开良滤空间。我们证明的主要结果包括:(1)每个良滤空间都是开良滤空间;(2)每个核紧的开良滤空间都是 sober 空间。作为直接推论,我们得出每个核紧的良滤空间都是 sober 空间。这为回答贾和容提出的开放问题提供了另一种不同且相对更直接的方法:每个核紧的良滤空间是否都是 sober 空间?

英文摘要:

We introduce and study a new class of $T_0$ spaces, called open well-filtered spaces. The main results we proved include (1) every well-filtered space is an open well-filtered space; (2) every core-compact open well-filtered space is sober. As an immediate corollary, we deduce that every core-compact well-filtered space is sober. This provides another different and relatively more straight forward method to answer the open problem posed by Jia and Jung: Is every core-compact well-filtered space sober?
