Nano-Zagreb Index and Multiplicative Nano-Zagreb Index of Some Graph Operations [PDF]
, 2019 Let G be a graph with vertex set V(G) and edge set E(G). The Nano-Zagreb and multiplicative Nano-Zagreb indices of G are NZ(G) = \prod_{uv \in E(G)} (d^2(u) - d^2(v)) and N*Z(G) = \prod_{uv \in E(G)} (d^2(u) - d^2(v)), respectively, where d(v) is the ...

First and Second Zagreb Eccentricity Indices of Thorny Graphs
, 2017 The Zagreb eccentricity indices are the eccentricity reformulation of the Zagreb indices. Let H be a simple graph. The first Zagreb eccentricity index ( E 1 ( H ) ) is defined to be the summation of squares of the eccentricity of vertices,

Computing entire Zagreb indices of some dendrimer structures
Main Group Metal Chemistry, 2020 Topological indices are numerical numbers associated to molecular graphs and are invariant of a graph. In QSAR/QSPR study, Zagreb indices are used to explain the different properties of chemical compounds at the molecular level mathematically.

Entropies and Degree-Based Topological Indices of Generalized Sierpiński Graphs
Fractal and FractionalFractals are geometric patterns that appear self-similar across all length scales and are constructed by repeating a single unit on a regular basis. Entropy, as a core thermodynamic function, is an extension based on information theory (such as Shannon ...

Inverse problem for Zagreb indices
, 2018 The inverse problem for integer-valued topological indices is about the existence of a graph having its index value equal to a given integer. We solve this problem for the first and second Zagreb indices, and present analogous results also for the ...

Extremal values on Zagreb indices of trees with given distance k-domination number
Journal of Inequalities and Applications, 2018 Let G = ( V ( G ) , E ( G ) ) $G=(V(G),E(G))$ be a graph. A set D ⊆ V ( G ) $D\subseteq V(G)$ is a distance k-dominating set of G if for every vertex u ∈ V ( G ) ∖ D $u\in V(G)\setminus D$ , d G ( u , v ) ≤ k $d_{G}(u,v)\leq k$ for some vertex v ∈ D $v ...
