S. Murugesan, J. Shiama . Square Difference 3-Equitable Labeling of Some Graphs. International Journal of Computer Applications. 137, 13 ( March 2016), 1-4. DOI=10.5120/ijca2016909018
A square difference 3-equitable labeling of a graph G with vertex set V is a bijection f from V to {1,2,...,|V|} such that if each edge uv is assigned the label -1 if |[f(u)]2 - [f(v)]2 ≡ -1(mod4), the label 0 if |[f(u)]2 - [f(v)]2|≡0(mod 4) and the label 1 if |[f(u)]2 - [f(v)]2|≡1(mod 4), then the number of edges labeled with i and the number of edges labeled with j differ by atmost 1 for -1≤i,j≤1. If a graph has a square difference 3-equitable labeling, then it is called square difference 3-equitable graph. In this paper, we investigate the square difference 3-equitable labeling behaviour of middle graph of paths, fan graphs, (P2n, S1), mK3, triangular snake graphs and friendship graphs.
