Sober spaces

Authors: MEHMET BARAN, HASSAN ABUGHALWA

Abstract: The goal of this paper is to introduce various forms of sober objects in a topological category and investigate the relationships among these various forms. Moreover, we characterize quasi-sober objects, $T_{0}$ objects and each of various forms of sober objects in some topological categories and give some invariance properties of them. Finally, we compare our results with some well-known results in the category of topological spaces.

Keywords: Topological category, $T_{0}$ objects, $T_{1}$ objects, sober spaces, irreducible spaces
