Lower Separation Axioms for X-top Lattices

General Topology 2025-10-28 v1

Abstract

We study separation axioms for XX-top-lattices (i.e. lattices LL for which a given subset XL\{1}X\subseteq L\backslash \{1\} admits a \emph{Zariski-like topology}). Such spaces are T0T_{0} and usually far away from being T2.T_{2}.% We give graphical characterizations for an XX-top-lattice to be T1,T_{1}, % T_{\frac{1}{4}}, T12,T_{\frac{1}{2}}, T34T_{\frac{3}{4}} and provide several families of examples/counterexamples that illustrate our results. We apply our results mainly to the prime (resp. maximal, minimal) spectra of prime (resp. maximal, minimal) ideals of commutative (semi)rings.
