Path and Star Related Graphs on Even Sequential Harmonious, Graceful, Odd Graceful and Felicitous Labelling

Abstract

In this paper, we prove that the D 2 (P n ) is an even sequential harmonious and graceful graph, D 2 (K 1 , n) an even sequential harmonious, graceful graph, odd graceful and felicitous graph, spl(P n ) is an even sequential harmonious and odd graceful graph, spl(K 1 , n) is an even sequential harmonious and felicitous graph.
