Degree-Based Topological Indices of the Jacobson Graph of Zm×Zn×Zr
Journal of MathematicsLet R be a commutative ring with unity. The Jacobson graph IR of R is an undirected simple graph whose vertex set is R\JR, where JR is a Jacobson ideal of R, and for any distinct vertices x,y∈R\JR are adjacent if and only if 1−xy is not a unit of R.

On the fourth atom-bond connectivity index of nanocones
Atom bond connectivity index is a topological index was defined as ABC(G) = Sigma(UV is an element of E(G)) root d(u)+d(v)-2/d(u)d(v) where d(v) denotes the degree of vertex v of G. Recently, M. Ghorbani et al.

On atom-bond connectivity index and its chemical applicability
, 2012 690-694A critical re-examination confirms that the atom-bond connectivity index (ABC) is well reproducing the heats of formation of alkanes (H°f). Moreover, the simple empirical formula H°f = – (a+b·ABC), with a = 65.98, b = 20.37, reproduces ...

Extreme Atom-Bond Connectivity Index of Graphs
, 2011 NSFC [10831001]The atom-bond connectivity (ABC) index of a graph G, is defined as the sum of the weights (d(u) + d(v) - 2/d(u)d(v))(1/2) of all edges uv of G, where d(u) denotes the degree of a vertex u in G.

Advanced Materials, EarlyView.ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

The fifth version of atom bond connectivity index (ABC(5)) of an infinite class of dendrimers
, 2011 The atom-bond connectivity index-5(ABC(5)) is a new topological index defined as; ABC(5)(G) = Sigma(uv is an element of E(G)) root M-u + M-v - 2/MuMv where M-u denotes the product of the degrees of adjacent vertices of u.
