• AMALGAMATION OF EVEN HARMONIOUS GRAPHS WITH STAR GRAPHS

Abstract

A graph G (V, E) with ‘n’ vertices and ‘m’ edges is said to be even harmonious graph if f is an injection from the vertices of G to the integers from 0 to 2q such that the induced mapping f* from the edges of G to {0, 2, 4,…2(q-1)} defined by f*(uv) = [f (u) + f (v)](mod 2q) is bijective.
