In this paper, we introduce the concepts of delta generalized closed, generalized delta closed and delta star generalized closed sets in bitopological spaces and study some of its properties and its relations with other types of closed sets. Also we study some properties of weak forms of separation axioms.

bitopological space, ij-δg-closed set, ij-gδ-closed set, ij-δg^*-closed set, ij-T_3/4-space, pairwise T_1/2 space, pairwise almost weakly Hausdorff space, pairwise T_δ space.
