S. Murugesan, D. Jayaraman, J. Shiama . Some Polygonal Sum Labeling of Paths. International Journal of Computer Applications. 62, 5 ( January 2013), 30-34. DOI=10.5120/10078-4692
A (p,q) graph G is said to admit a polygonal sum labeling if its vertices can be labeled by non -negative integers such that the induced edge labels obtained by the sum of the labels of end vertices are the first q polygonal numbers. A graph G which admits a polygonal sum labeling is called a polygonal sum graph. In this paper we prove that the paths admit pentagonal, hexagonal, heptagonal, octagonal, nonagonal and decagonal sum labeling. This work is a nice composition of graph theory and combinatorial number theory.
