Cubic Harmonious Labeling Of Certain Star and Bistar Graphs
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 11
Abstract
A (n,m) graph G =(V,E) is said to be Cubic Harmonious Graph(CHG) if there exists an injective function f:V(G)→{1,2,3,………m3+1} such that the induced mapping f * chg: E(G)→ {13 ,23 ,33 ,……….m 3 } defined by f * chg (uv) = (f(u)+f(v)) mod (m3+1) is a bijection. we have proved that star and bistar related graphs are cubic harmonious
