Some Study on the Topological Structure on Semigroups

Abstract

Some studies related to the topological structure of semigroups are provided. In, [3], considering and investigating the properties of the collection A of all the proper uniformly strongly prime ideals of a Γ - semigroup S, such study starts by constructing a topology τA on A using a closure operator defined in terms of the intersection and inclusion relation among these ideals of Γ-semigroup S, which is a generalization of the semigroup. In this paper, we introduce three other classes of ideals in semigroups called maximal ideals, prime ideals and strongly irreducible ideals, respectively. Investigating properties of the collection M, B and S of all proper maximal ideals, prime ideals and strongly irreducible ideals, respectively, of a semigroup S, we construct the respective topologies on them. The respective obtained topological spaces are called the structure spaces of the semigroup S. We study several principal topological axioms and properties in those structure spaces of semigroup such as separation axioms, compactness and connectedness, etc.
