This review consists of four parts, each treating a different aspect of chemical graph theory:(i)
recent developments in molecular connectivity theory,(ii) drug design using a chemical …

Divided into five sections, this book offers 200 graph-theoretical matrices covering
adjacency and related matrices, distance and related matrices, incidence matrices, and …

Graph theory [12, 83, 86] is a relatively new branch of mathematics and the main body of
fundamental results dates back to the seminal contribution due to König [111]. Earlier …

Counting polynomials are those polynomials having at exponent the extent of a property
partition and coefficients the multiplicity/occurrence of the corresponding partition. In the …

A new counting polynomial, called “Omega” Ω (G, x), was recently proposed by Diudea. It is
defined on the ground of quasi-orthogonal cut “qoc” edge strips. Three topological …

A correlating study of topological indices TIs provided by TOPOCLUJ software package and
LEL, a newly proposed index built up on the eigenvalues of Laplacian matrix, on thirteen …

Omega polynomial was proposed by Diudea (Omega Polynomial, Carpath. J. Math., 2006,
22, 43–47) to count the opposite topologically parallel edges in graphs, particularly to …

Creating new nanostructures as potential carriers of drugs is an important goal nowadays.
Among many real or hypothetical polymeric networks, the etheric ones are very promising, in …

A possible extension of Zagreb indices to weighted graphs representing heterosystems is
presented. It is based on the novel definition of the Zagreb indices by way of the here …
