Soft Closed Sets on Soft Bitopological Space

Abstract

Soft set theory was introduced by Molodtsov as ageneral mathematical tool for dealing with problems that containuncertainity. In this paper, on soft bitopological space, we definesoft closed sets; soft α-closed, soft semi-closed, soft pre-closed,regular soft closed, soft g-closed and soft sg-closed. We also giverelated properties of these soft sets and compared their propertieswith each other
