On square sum graphs
A (p, q)-graph G is said to be square sum, if there exists a bijection f : V(G) - {0,1, 2,...,p - 1} such that the induced function f * : E(G) - N given by f * (uv) = (f (u))² + (f (v))² for every uv G E(G) is injective. In this paper we initiate a study on square sum graphs and prove that trees, un...
