Augmented Zagreb Index of Corona Product of Some Special Graphs

Abstract

Let be a simple undirected graph. The Augmented Zagreb Index of a graph is defined as , Where is the degree of the vertex in . In this paper, the exact expression for Augmented Zagreb Index of different product of graphs like Comb, Wheel, Fan,andSun graph.

Introduction

Conclusion

In this paper, Augmented Zagreb index of corona product of graphs are discussed. Some special graphs have been proved under Augmented Zagreb index of corona product of graphs. This index can be use as a numerical description with chemical, physical and biological parameters to study about its relationships.
