Remarks on Closure and Interior Operators in Bitopological Spaces

Abstract

Andrijevic and his collaborators studied the various aspects of closure and interior operators in general topological spaces and obtained several relations among them. Researchers in general topology studied such operators in bitopological settings. Andrijevic established that the result clA=Acl(int(clA)) holds for any subset A of a topological space where clA, clA and intA denote the -closure of A, closure of A and interior of A respectively. He also established the analog results for other operators in terms of the closure and interior operators in general topological spaces. In this paper we discuss the analog results in bitopological settings.
