4-Difference Cordial Labeling of Cycle and Wheel Related Graphs


S. M. Vaghasiya, G. V. Ghodasara
Abstract

Let G be a (p, q) graph. Let k be an integer with 2 ≤ k ≤ p and f : V (G) → {1, 2, . . . k} be a map. For each edge uv, assign the label |f(u) − f(v)|. The function f is called a k-difference cordial labeling of G if |vf (0) − vf (1)| ≤ 1 and |ef (0) − ef (1)| ≤ 1 where vf (x) denotes the number of vertices labelled with x (x ∈ {1, 2, . . . , k}), ef (1) and ef (0) respectively denote the number of edges labelled with 1 and not labelled with 1. A graph with a k-difference cordial labeling is called a k-difference cordial graph. In this paper we discuss 4-difference cordial labeling for cycle, wheel, crown, helm and gear graph.

Keywords
