This paper presents new classes of open and closed functions defined between bitopological spaces, called weakly (τ1, τ2)p-open functions and weakly (τ1, τ2)p-closed functions. Furthermore, several characterizations of weakly (τ1, τ2)p-open functions and weakly (τ1, τ2)p-closed functions are investigated.
Pue-on et al. (Fri,) studied this question.
