Abstract

An k-edge-weighting of a graph G=(V,E) is a map φ: E(G) → {1, 2, 3, ..., k} where k ≥ 1 is an integer. Denote Sφ(v) is the sum of edge-weights appearing on the edges incident at the vertex v under φ.  An k-edge-weighting of G is equitable irregular if |Sφ (u)−Sφ (v)| ≤ 1, for every pair of adjacent vertices u and v in G. Theequitable irregular strength of an equitable irregular graph G is the smallest positive integer k such that there is a k-edge weighting of G and is denoted by Se (G). In this paper, we discuss the equitable irregularity of Polar grid and Mongolian tent graphs
