On the Hyper Zagreb Index of Trees With a Specified Degree of Vertices

open access: yesSymmetry, 2023
Topological indices are the numerical descriptors that correspond to some certain physicochemical properties of a chemical compound such as the boiling point, acentric factor, enthalpy of vaporisation, heat of fusion, etc. Among these topological indices,

Hyper Zagreb Indices of Composite Graphs

open access: yesInternational Journal of Advanced Mathematical Sciences, 2016
For a (molecular) graph, the first Zagreb index M1 is equal to the sum of squares of the degrees of vertices, and the second Zagreb index M2 is equal to the sum of the products of the degrees of pairs of adjacent vertices.

Applications on Hyper-Zagreb Index of Generalized Hierarchical Product Graphs

open access: yesJournal of Computational and Theoretical Nanoscience, 2016
Let G be a connected graph. The Hyper-Zagreb index of a connected graph G is defined as HM(G) = Σuv∈EG [dG(u)+dG(v)]2, where dG(v) is the degree of the vertex v in G.
