Upper Bounds of AZI and ABC Index for Transformed Families of Graphs [PDF]
Mathematical Problems in Engineering, 2022 Topological index is a mapping which corresponds underlying graph with a numeric value and invariant up to all the isomorphisms of graph. Our study is based on a partial open question regarding topological indices: for which members of n-vertex graph family, certain index has minimum or maximum value?

On the Minimum ABC Index of Chemical Trees
Journal on Applied Mathematics, 2012 The Atom Bond Connectivity index, also known as ABC index was defined by Estrada(4) with relation to the energy of formation of alkanes. It was quickly recognized that this index reflects important structural properties of graphs in general. The ABC index was extensively studied in the last three years, from the point of view of chemical graph theory(5,

The (ABC) Conjecture and the radical index of integers [PDF]
Acta Arithmetica, 2001 The author introduces a new definition: the \textit{radical index} \(\nu(n)\) of an integer \(n\) with \(|n|>1\) which is given by the formula \(|\text{rad} (n)|^{\nu(n)}=|n|\) where, as usual, \(\text{rad} (n)=\prod_{p \mid n}p\). Then this concept is used in relation to the \((ABC)\) conjecture.

Further Properties of Trees with Minimal Atom-Bond Connectivity Index
Abstract and Applied Analysis, 2014 Let G=(V,E) be a graph the atom-bond connectivity (ABC) index is defined as the sum of weights ((du+dv-2)/dudv)1/2 over all edges uv of G, where du denotes the degree of a vertex u of G. In this paper, we determined a few structural features of the trees
