K-Even Sequential Harmonious Labeling of Some Cycle Related Graphs

Graham and Sloane [6] introduced the harmonious graphs and Singh & Varkey [7] 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]. Here, we investigate the k-even sequential harmonious labeling of some cycle related graphs.
