## On topological lattices and their applications to module theory.(English)Zbl 1343.06005

In this quite interesting paper, the authors study topological lattices relative to a proper subset of the lattice and study its properties. Next apply these results to study properties of modules. After introduction and preliminaries in Section 1, in Section 2, for a complete lattice $$\mathcal L=(L,\wedge,\vee,0,1)$$ and a proper subset $$X$$ of $$L-\{1\}$$, they consider $$X$$-top lattices. Their main theorem in this section is that $$\mathcal L$$ is an $$X$$-top lattice if and only if every element of $$X$$ is strongly irreducible in $$(C(L),\wedge)$$. In Section 3, they introduce prime modules and first submodules of a module, as a dual to second submodules, and derive some equivalent conditions for a first submodule of a module. In the main Section 4, for an $$R$$-module $$M$$, they define a topology on the set $$\mathrm{Spec}^f(M)$$ of all first submodules of $$M$$. If with this topology the dual lattice $$\mathcal L(M)^\circ$$ is a $$\mathrm{Spec}^f(M)$$-top lattice then they call $$M$$ to be a $$\mathrm{top}^f$$-module. If every first submodule of $$M$$ is strongly hollow then $$M$$ is said to be strongly $$\mathrm{top}^f$$-module. The authors derive some module theoretic properties of $$\mathrm{top}^f$$-modules and strongly $$\mathrm{top}^f$$-modules $$M$$ in terms of topological properties of $$\mathrm{Spec}^f(M)$$.
