On Soft Preopen Sets and Soft Pre Separation Axioms

Arockiarani and Lancy [7], defined soft pre-open insert ignore into journalissuearticles values(closed); sets on soft topology. In this paper, we are continue investigating the properties of soft pre-open insert ignore into journalissuearticles values(closed); sets and define soft preclosure and soft preinterior in soft topological spaces. We are also introduce and research basic properties of the concepts of soft pre-regular spaces, soft P₃-spaces, soft pre-normal spaces and soft P₄-spaces in soft topological spaces, which are basic for further research on soft topology and will fortify the footing of the theory of soft topological space.
