Difference divisor graph of the finite group
Let (Zn, +) be a Face Paints finite group of integers modulo n and Dn a non-empty subset of Zn containing proper devisors of n.In this paper, we have introduced the difference divisor graph Diff (Zn, Dn) associated with Zn whose vertices coincide with Zn such that two distinct vertices are adjacent if and only if either a-b belongs to Dn or b-a bel
