Coleman关于散点集的一个问题的解答

An answer to a question of Coleman on scattered sets

Julian Dontchev, Maximilian Ganster

摘要:

本文的目的是证明自稠密半$T_D$ -空间的每个离散子集在任何地方都是稠密的。因此,我们能够肯定地回答科尔曼最近提出的一个问题。利用数字拓扑理论,证明了在没有开屏的半$T_D$ -空间中,迹空间没有并构.

英文摘要:

The aim of this paper is to show that every scattered subset of a dense-in-itself semi-$T_D$-space is nowhere dense. We are thus able to answer a recent question of Coleman in the affirmative. In terms of Digital Topology, we prove that in semi-$T_D$-spaces with no open screen, trace spaces have no consolidations.
