Abstract

This paper presents new classes of functions defined between bitopological spaces, namely weakly θ(τ1, τ2)s-open functions and weakly θ(τ1, τ2)s-closed functions. Moreover, several characterizations of weakly θ(τ1, τ2)s-open functions and weakly θ(τ1, τ2)s-closed functions are established.
