Computing zagreb indices and zagreb polynomials of fullerene, butterfly and benes networks
, 2019 A topological index is a numerical parameter of a graph which characterizes some of the topological properties of the graph. The concepts of hyper-Zagreb index, first multiple Zagreb index, second multiple Zagreb index and relatedly the Zagreb ...

Hyper Zagreb Index of Bridge and Chain Graphs
Open Journal of Mathematical Sciences, 2018 Let G be a simple connected molecular graph with vertex set $V(G)$ and edge set $E(G)$. One important modification of classical Zagreb index, called hyper Zagreb index $HM(G)$ is defined as the sum of squares of the degree sum of the adjacent vertices, that is, sum of the terms $[{d_G}(u)+{d_G}(v)]^2$ over all the edges of $G$, where ${d_G}(u)$ denote ...

On some topological indices of zero divisor graphs of direct product of three finite fields
Examples and CounterexamplesIn this paper, we determine some degree-based topological indices, such as the Sombor index, the first and second Zagreb indices, the forgotten topological index, the Narumi–Katayama index, the first and second multiplicative Zagreb indices, the atom ...

Zagreb-Based Indices of Line Graph of Prime Coprime Graph for Integers Modulo Group
Science and Technology IndonesiaIn this paper, we investigate the line graph of the prime coprime graph associated with the integers modulo group. Explicit general formulas are derived for the first Zagreb index, the second Zagreb index, and the hyper-Zagreb index of the considered ...

A lower bound for the first Zagreb index and its application [PDF]
, 2015 For a graph G, the first Zagreb index is defined as the sum of the squares of the vertices degrees. By investigating the connection between the first Zagreb index and the first three coefficients of the Laplacian characteristic polynomial, we give a ...
