Upper Bounds of AZI and ABC Index for Transformed Families of Graphs [PDF]

open access: yesMathematical 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?

Analogy-Based Crop Yield Forecasts Based on Temporal Similarity of Leaf Area Index

open access: yesRemote Sensing, 2021
Seasonal forecasts of crop yield are important components for agricultural policy decisions and farmer planning. A wide range of input data are often needed to forecast crop yield in a region where sophisticated approaches such as machine learning and ...

Comparing the excepted values of atom-bond connectivity and geometric–arithmetic indices in random spiro chains

open access: yesJournal of Inequalities and Applications, 2018
The atom-bond connectivity (ABC) index and geometric–arithmetic (GA) index are two well-studied topological indices, which are useful tools in QSPR and QSAR investigations.

On the Minimum ABC Index of Chemical Trees

open access: yesJournal 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]

open access: yesActa 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

open access: yesAbstract 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
