Let Γ(Zn) be a bipartite graph. A subset D of V (Γ(Zn)) is a bipartite universal dominating set of Γ(Zn) if D is a dominating set of Γ(Zn) and Γ(Zn)b .The minimum cardinality of a bipartite universal dominating set of Γ(Zn) is called the bipartite universal domination number of Γ(Zn) and is denoted by γbu(Γ(Zn)). In this paper,we introduce bipartite universal domination number of zero divisor graphs and we study about the structure of this parameter in Γ(Zn). © 2015 K. Ananthi, J. Ravi Sankar and N. Selvi.
