准T2空间

Pre-Hausdorff Spaces

Jay Stine, M. V. Mielke

摘要:

本文引入了拓扑空间的三个分离条件,称为T_{0,1},T_{0,2}(“pre-Hausdorff”)和T_{1,2} .这些条件推广了经典的T_(1)和T_(2)分离性公理,并在拓扑上优于我们讨论的T_(1)和T_(2)分离性公理。建立了准T2空间的几种不同的刻画,并给出了T2空间的准Hausdorff刻画.本文还讨论了一般拓扑学中的一些经典定理,它们可以或不能通过用pre-Hausdorff条件代替Hausdorff条件而得到推广。

英文摘要:

This paper introduces three separation conditions for topological spaces, called T_{0,1}, T_{0,2} ("pre-Hausdorff"), and T_{1,2}. These conditions generalize the classical T_(1) and T_(2) separation axioms, and they have advantages over them topologically which we discuss. We establish several different characterizations of pre-Hausdorff spaces, and a characterization of Hausdorff spaces in terms of pre-Hausdorff. We also discuss some classical Theorems of general topology which can or cannot be generalized by replacing the Hausdorff condition by pre-Hausdorff.
