Abstract

This paper presents new classes of open and closed functions defined between bitopological spaces,
called weakly $\theta(\tau_1,\tau_2)b$-open functions and weakly $\theta(\tau_1,\tau_2)b$-closed
functions. Moreover, several characterizations and some properties concerning weakly
$\theta(\tau_1,\tau_2)b$-open functions and weakly $\theta(\tau_1,\tau_2)b$-closed functions are
established.
