On $u-\omega$-Open and $q-\omega$-Open Sets in Bitopological Spaces

Abstract

$\omega$-open sets are used to introduce two new classes of sets in bitopological spaces, namely, $u-\omega$-open sets and $q-\omega$-open sets. Several properties of these classes are given. The new classes of sets are used to introduce several types of continuity. Several results related to two known Lindelöfness bitopological concepts are introduced.
