The Hyper-Zagreb Index of Trees and Unicyclic Graphs
Hassan Rezapour, Ramin Nasiri, Seyedahmad Mousavi
Abstract:  
Topological indices are widely used as mathematical tools to analyze different types of graphs emerged in a broad range of applications. The Hyper-Zagreb index (HM) is an important tool because it integrates the first two Zagreb indices. In this paper, we characterize the trees and unicyclic graphs with the first four and first eight greatest HM-value, respectively.
Keywords: Hyper-Zagreb index, Vertex degree, Unicyclic graphs, Trees.
