Zagreb indices and multiplicative zagreb indices of double graphs of subdivision graphs
, 2019 Let G be a simple graph. The subdivision graph and the double graph are the graphs obtained from a given graph G which have several properties related to the properties of G. In this paper, the first and second Zagreb and multiplicative Zagreb indices of double graphs, subdivision graphs, double graphs of the subdivision graphs and subdivision graphs ...

Hyper Zagreb indices of composite graphs
, 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.

On the Zagreb indices as complexity indices
, 2000 Two original Zagreb indices, denoted M(1) and M(2), and introduced in 1972, were symmetry-modified by summing up only degrees (SMM(1)) or edge-weights (SMM(2)) of symmetry nonequivalent vertices or edges of graphs. Their dependence on the structural features and symmetry of molecular graphs is studied.

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 ...

Zagreb indices of square snake graphs
, 2021 Several lattice structures that can be thought as graphs are useful in the study of large networks. In this work, we study 15 topological graph indices from the class of Zagreb indices of some interesting lattice structures called snake graphs.
