On Topological Lattices and an Application to First Submodules

Abstract

We introduce the notion of a (strongly) topological lattice $\mathcal{L}=(L,\wedge ,\vee )$ with respect to a subset $X⫋L;$ aprototype is the lattice of (two-sided) ideals of a ring $R,$ which is(strongly) topological with respect to the prime spectrum of $R.$ We investigate and characterize (strongly) topological lattices. Given a non-zero left $R$-module $M,$ we introduce and investigate the spectrum ${\mathrm{Spec}}^{\mathrm{f}}(M)$ of \textit{first submodules} of $M.$ We topologize ${\mathrm{Spec}}^{\mathrm{f}}(M)$ and investigate the algebraic properties of ${}_{R}M$ by passing to the topological properties of the associated space.
