Abstract :
In this paper we introduce and study the notions of θij-cluster sets and θij-closed graphs for functions between bitopological spaces. Several new characterizations of θij-cluster sets and θij-closed graphs are given in terms of θij-closed sets and %-convergence of nets and filters. Conditions for degeneracy of θij-cluster sets are found
