On tricyclic graphs with maximum atom–bond sum–connectivity index

open access: yesHeliyon
The sum-connectivity, Randić, and atom-bond connectivity indices have a prominent place among those topological indices that depend on the graph's vertex degrees. The ABS (atom-bond sum-connectivity) index is a variant of all the aforementioned three indices, which was recently put forward.

The Atom-Bond Connectivity Index of Catacondensed Polyomino Graphs [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2013
LetG=(V,E)be a graph. The atom-bond connectivity (ABC) index is defined as the sum of weights((du+dv−2)/dudv)1/2over all edgesuvofG, wheredudenotes the degree of a vertexuofG. In this paper, we give the atom-bond connectivity index of the zigzag chain polyomino graphs.

Atom–bond connectivity index of trees

open access: yesDiscrete Applied Mathematics, 2009
The recently introduced atom-bond connectivity (ABC) index has been applied up to now to study the stability of alkanes and the strain energy of cycloalkanes. Here, mathematical properties of the ABC index of trees are studied. Chemical trees with the extremal ABC values are found. In addition, it has been proven that among all trees, the star tree, Sn,

On atom-bond connectivity index

open access: yesChemical Physics Letters, 2011
The atom-bond connectivity index (ABC) is a vertex-degree based graph invariant, put forward in the 1990s, having applications in chemistry. Let G = (V,E) be a graph, di the degree of its vertex i, and ij the edge connecting the vertices i and j. Then ABC = ?ij?E ?(di+dj?2)/(didj).

Remarks on Multiplicative Atom-Bond Connectivity Index [PDF]

open access: yesIEEE Access, 2019
The atom-bond connectivity (ABC) index is one of the most actively studied degree-based graph invariants that are found in a vast variety of chemical applications. This paper is devoted to establishing some extremal results regarding the variant of the ABC index, the so-called multiplicative ABC index (ABC$\Pi $ ), which, for a graph $G$ , is defined ...
