k-Odd Sequential Harmonious Labeling of Some Special Graphs

B. Gayathri, D. Muthuramakrishnan

Abstract: Graham and Sloane [7] introduced the harmonious graphs and Singh & Varkey [8] introduced the odd sequential graphs. Gayathri & Hemalatha [2] introduced even sequential harmonious labeling of graphs. We studied even sequential harmonious labeling of trees in [3]. In [4], we have extended this notion to k-even sequential harmonious labeling graphs. It is further studied in [5]. k-even sequential harmonious labeling of some cycle related graphs are studied in [6]. Also, we have introduced k-odd sequential harmonious labeling of graphs in [5]. In this paper, we investigate k-odd sequential harmonious labeling of some special graphs.
