On minimum generalized ABC index of graphs

Filomat
The generalized ABC index of a graph G, denoted by ABC?, is defined as the sum of the terms [(d(v) + d(u)-2)/d(v)d(u)]? over all pairs of adjacent vertices, where d(u) is the degree of the vertex u and ? is a real number. In this paper, we prove that for

ABC of Content Validation and Content Validity Index Calculation

Education in Medicine Journal, 2019
There are five sources of validity evidence that are content, response process, internal structure, relation to other variables, and consequences. Content validity is the extent of a measurement tool represents the measured construct and it is considered

Product Connectivity Leap Index and ABC Leap Index of Helm Graphs

Annals of Pure and Applied Mathematics, 2018
Recently, some leap Zagreb indices of a graph based on the second degrees of vertices were introduced. In this paper, we propose the product connectivity leap index and ABC leap index of a graph.

ASSOCIATION OF ABC-INDEX WITH OTHER TOPOLOGICAL INDICES

International Journal of Applied Mathematics
 A graph's links as well as verges determine its atom-bond-connectivity indicator. This study highlights key findings on the Atom bond indicator. The study explores the Atom bond indicator indicator's findings, paying particular attention to its degrees,

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.

Characterizing Trees with Minimal ABC Index with Computer Search: A Short Survey

Open Journal of Discrete Applied Mathematics, 2018
. The atom-bond connectivity ( ABC ) index of a graph G = ( V;E ) is defined as ABC ( G ) = ∑ v i v j 2 E √ ( d i + d j (cid:0) 2) = ( d i d j ), where d i denotes the degree of vertex v i of G .

On the maximal general ABC index of graphs with given maximum degree

Applied Mathematics and Computation, 2020
The atom-bond connectivity index ABC is a topological index that has recently found remarkable applications in the study of the strain energy of cycloalkanes as well as in rationalizing the stability of linear and branched alkanes. In order to improve the correlation properties of the atom-bond connectivity index for the heat of formation of alkanes ...
