Abstract
A (p, q) graph G is called an edge trimagic graceful if there exists a bijection f : V(G) ? E(G) ? {1, 2, 3, …, p + q} such that for each edge xy in E(G), |f (x) – f (xy) + f (y)? = C1 or C2 or C3, where C1, C2 and C3 are constants. In this paper, we proved that the bistar, double star, triple star graph are edge trimagic graceful graphs.
