Some properties of the reformulated Zagreb indices

Journal of Mathematical Chemistry, 2010
Miliević, Nikolić and Trinajstić (Mol Divers 8:393-399, 2004) proposed the reformed Zagreb indices in 2004. Now we give some properties for the reformed Zagreb indices.

\(F\)-sums of graphs and their reformulated-Zagreb indices

2021
Summary: The reformulated Zagreb index \(EM_1(G)\) of a simple graph \(G\) is defined as the sum of the terms \((d_u + d_v - 2)^2\) over all edges \(uv\) of \(G\). In this paper, we study the reformulated Zagreb indices for the \(F\)-sums of some special well-known graphs such as subdivision and total graph which is introduced by \textit{M. Eliasi} and

Four New Operations Related to Composition and Their Reformulated Zagreb Index

Indonesian Journal of Combinatorics, 2018
The first reformulated Zagreb index EM1(G) of a simple graph G is defined as the sum of the terms (du+dv-2)2 over all edges uv of G. In 2017, Sarala et al. introduced four new operations (F-product) of graphs.

Computing Zagreb Indices and Zagreb Polynomials for Symmetrical Nanotubes

Symmetry, 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 ...

On the first reformulated Zagreb indices of graphs with a given clique number.

Ars Comb., 2018
Summary: \textit{A. Miličević} et al. [``On reformulated Zagreb indices'', Molecular Diversity 8, No. 4, 393--399 (2004)] introduced the reformulated Zagreb indices, which is a natural generalization of classical Zagreb indices in chemical graph theory.
