Dr. A. Manonmani, R. Savithiri

Abstract: Singh and Varkey introduced the odd sequential graphs. Gayathri and Hemalatha introduced even sequential harmonious labeling of graphs and also k-even sequential harmonious labeling of graphs. Here, we investigate some new results on k-even sequential harmonious labeling of graphs. In this paper, we have shown that the graphs Pn3, Alternate triangular snakes and Alternate quadrilateral snakes are k-even sequential harmonious graphs.

Keywords: Path, Alternate triangular snake, Alternate quadrilateral snak
