Abstract

The augmented Zagreb index (AZI) of graph is defined as the sum of weights of all edges uv of a graph G , where the weight of edge uv is calculated as (d(u)d(v) / d(u)+d(v)−2) 3 . In this paper, we examine the (maximum) AZI for graphs with edge connectivity one and examine the relative extremal graphs. MSC: 5C35.
