On the Trees With Maximal Augmented Zagreb Index
IEEE Access, 2018 The augmented Zagreb index (AZI), a variant of the well-known atom-bond connectivity (ABC) index, was shown to have the best predicting ability for a variety of physicochemical properties among several tested vertex-degree-based topological indices.

Bounds for the augmented Zagreb index
Theory and Applications of Graphs, 2023 Summary: The augmented Zagreb index (AZI for short) of a graph \(G\), introduced by \textit{B. Furtula} et al. [J. Math. Chem. 48, No. 2, 370--380 (2010; Zbl 1196.92050)] is defined as AZI\((G)=\sum_{v_iv_j\in E(G)}\left(\frac{d(v_i)d(v_j)}{d(v_i)+d(v_j)-2}\right)^3\), where \(E(G)\) is the edge set of \(G\), and \(d(v_i)\) denotes the degree of the ...

Sharp Bounds of the Hyper-Zagreb Index on Acyclic, Unicylic, and Bicyclic Graphs
Discrete Dynamics in Nature and Society, 2017 The hyper-Zagreb index is an important branch in the Zagreb indices family, which is defined as ∑uv∈E(G)(d(u)+d(v))2, where d(v) is the degree of the vertex v in a graph G=(V(G),E(G)). In this paper, the monotonicity of the hyper-Zagreb index under some

The hyper-Zagreb index of cacti with perfect matchings [PDF]
AKCE International Journal of Graphs and Combinatorics, 2020 Let be a simple connected graph. The hyper-Zagreb index is defined as . A connected graph is a cacti if all blocks of are either edges or cycles. Let be the set of cacti of order with a perfect matching and cycles. In this paper, we determine sharp upper bounds of the hyper-Zagreb index of cacti among and characterize the corresponding extremal cacti.
