QUAD DIFFERENCE LABELLING ON SOME GRAPHS
Keywords:Square difference, Cube difference, Quad difference, Labelling, difference labelling
A new labelling and a new graph called quad difference labelling and quad difference graph is defined. Let G be a graph. G is said to be quad difference labelling if there exist such that the edge set of G has assigned a weight defined by the absolute quad difference of its end vertices, the resulting weights are distinct. We investigate quad difference labelling for some graphs. The approach will be to summarize them in different flavour and possible different labelling.
