$\psi^{*}\alpha$-Closed Sets in Bitopological Spaces


Keywords:
$\psi^{*}\alpha$-closed set, $\psi^{*}\alpha$-open set, $\psi$g-open set, $\tau_{i}$-open setAbstract
In this paper we introduce $\psi^{*}\alpha$-closed sets in bitopological spaces and obtain the relationship between the other existing closed sets. Also we study the notion of $(i, j)$-$\psi^{*}\alpha$-closure operator and some of its properties. As applications we introduce $(i, j)$-${}_{\psi^*\alpha}T_{c}$-space, $(i, j)$-${}_{\psi^*\alpha}T_{\alpha}$-space and study some of their properties.
