On Spec(M) Topology of Module M over Commutative Rings
Abstract
Let R be a commutative ring with unity and M be an R-module. In this study, we construct the Spec(M) topology using the prime spectrum of module M and multiplicatively closed subsets of R with the closed sets V(S)=P ∈ Spec(M) : (P : M) Si ≠ for all i ∈ I with the open sets D(Si):=P ∈ Spec(M) : (P : M) Si = where S = Sii ∈ I is a family of multiplicatively closed subsets of R. We investigate connections between the algebraic properties of R-module M and the topological properties of Spec(M). We examine specifically the separation axioms, connectivity, nested and Lindel\"of property together with quasi-compactness as well as the isolated, closure, interior and limit points of tildeSpec(M). Moreover, in the last section, we provide an example of a Lindel\"of space which is not quasi-compact by means of Spec(M).
