某些弱separation axioms的理想化

Idealization of some weak separation axioms

Francisco G. Arenas, Julian Dontchev, Maria Luz Puertas

摘要:

理想是在遗传和有限可加下闭子集的非空集合。本文的目的是通过拓扑理想统一一些弱分离性。我们集中我们的注意力在$T_0$和$T_2$之间的分离公理。证明了如果$(X,τ,{\cal I})$是半Alexandroff $T_{\cal I}$ -空间,$\cal I$是$τ$ -边界,则$\cal I$是完全余稠密的.

英文摘要:

An ideal is a nonempty collection of subsets closed under heredity and finite additivity. The aim of this paper is to unify some weak separation properties via topological ideals. We concentrate our attention on the separation axioms between $T_0$ and $T_2$. We prove that if $(X,τ,{\cal I})$ is a semi-Alexandroff $T_{\cal I}$-space and $\cal I$ is a $τ$-boundary, then $\cal I$ is completely codense.
