Graphs with Maximum Generalized Complementary Second Zagreb Index [PDF]
Match Communications in Mathematical and in Computer ChemistryIn this paper, we confirm a conjecture by Furtula and Oz regarding graphs that maximize the second complementary Zagreb index. We demonstrate that this conjecture holds for a broader class of indices, each of which is parameter-dependent, and which we will refer to as the generalized complementary second Zagreb index.

On hyper-Zagreb index conditions for hamiltonicity of graphs [PDF]
, 2022 summary:During the last decade, several research groups have published results on sufficient conditions for the hamiltonicity of graphs by using some topological indices. We mainly study hyper-Zagreb index and some hamiltonian properties.

On hyper–Zagreb index and coindex [PDF]
, 2017 Let G be a graph with vertex set V and edges set E. By d(v) is denoted the degree of its vertex v. Two much studied degree–based graph invariants are the first and second Zagreb indices.

On a Conjecture Concerning the Complementary Second Zagreb Index
Match Communications in Mathematical and in Computer ChemistryThe complementary second Zagreb index of a graph $G$ is defined as $cM_2(G)=\sum_{uv\in E(G)}|(d_u(G))^2-(d_v(G))^2|$, where $d_u(G)$ denotes the degree of a vertex $u$ in $G$ and $E(G)$ represents the edge set of $G$. Let $G^*$ be a graph having the maximum value of $cM_2$ among all connected graphs of order $n$. Furtula and Oz [MATCH Commun.

Computing Connection-Based Topological Indices of Sudoku Graphs
Journal of Mathematics, 2022 A topological index (TI) is a function that associates a numeric number to the under-study molecular graph. The first TI based on distance was presented by Wiener to find the boiling point of paraffins.

Topology-Based Analysis of OTIS (Swapped) Networks OKn and OPn
Journal of Chemistry, 2019 In the fields of chemical graph theory, topological index is a type of a molecular descriptor that is calculated based on the graph of a chemical compound. In this paper, M-polynomial OKn and OPn networks are computed.
