Soft Sets and Soft Topological Notions

Abstract

In this paper we extend the notions of operations on soft sets to arbitrary collection of soft sets

and introduce the concepts of F_{sigma}-soft set and G_{sigma} -soft set. Furthermore we give definitions of soft

locally finite, soft discrete, sigma-soft locally finite and sigma-soft closure preserving, relative to an arbitrary

collection of soft sets and study some of their properties

Keywords

• soft symmetric difference,soft perfect,relatively soft discrete,soft closed domain (regularly closed),soft open domain (regularly open)
