Beyond the Zagreb Indices [PDF]

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The two Zagreb indices and are vertex-degree-based graph invariants that have been introduced in the 1970s and extensively studied ever since. In the last few years, a variety of modifications of and were put forward. The present survey of these modified Zagreb indices outlines their main mathematical properties, and provides an exhaustive bibliography.

Computing Zagreb Indices and Zagreb Polynomials for Symmetrical Nanotubes [PDF]

open access: yesSymmetry, 2018
Topological indices are numbers related to sub-atomic graphs to allow quantitative structure-movement/property/danger connections. These topological indices correspond to some specific physico-concoction properties such as breaking point, security, strain vitality of chemical compounds.

On Reformulated Zagreb Indices

Molecular Diversity, 2004
Zagreb indices were reformulated in terms of the edge-degrees instead of the vertex-degrees as the original Zagreb indices. Three types of Zagreb indices were considered: original, modified and variable Zagreb indices. It is found that the optimum exponent of the variable reformulated Zagreb M2 index (v = -1/2) is identical with the exponent of the ...
