X-拓扑格的更高分离公理及其在交换(半)环中的应用

Higher Separation Axioms for $X$-top Lattices Applications to Commutative (Semi)rings

Jawad Abuhlail, Abdulmushin Alfaraj

AI总结:

本文研究了X-拓扑格的分离公理,探讨了其在交换(半)环素理想谱中的应用。

摘要:

我们研究了几种X-拓扑格(即一个格L,其中给定的子集X⊆L\{1\}允许一种类似扎里斯基拓扑的结构)的分离公理。此类空间是T₀的,通常远离成为T₂。我们为X-拓扑格提供充分/必要条件,使得X成为T₂、正则(T₃)、完全正则(T₃₁⁄₂)、正则、完全正则或完美正则(T₆)。我们主要将结果应用于交换(半)环素理想(resp. 最大、最小理想)的谱。我们通过多个例子/反例来说明我们的结果。

英文摘要:

We study several separation axioms for $X$-top-lattices (i.e. a lattice $L$ for which a given subset $X\subseteq L\backslash \{1\}$ admits a \emph{% Zariski-like topology}). Such spaces are $T_{0}$ and usually far away from being $T_{2}.$ We provide sufficient/necessary conditions for an $X$-top lattice so that $X$ is $T_{2},$ \emph{regular} ($T_{3}$), \emph{completely regula}r ($T_{3\frac{1}{2}}$), \emph{normal}, \emph{completely normal} or \emph{perfectly normal} ($T_{6}$). We apply our results mainly to the spectrum of prime (resp. maximal, minimal) ideals of a commutative (semi)ring. We illustrate our results with several examples/counterexamples.
