چکیده
|
The general sum-connectivity index of a graph g, denoted by xa= xa (g) is defined as xa=∑uvєe(g) (du+dv)a where du (or dv) is the degree of the vertex u (or v). efficient formulas for calculating the general sum-connectivity index of benzenoid systems and their phenylenes are given, and a relation is established between the general sum-connectivity index of a phenylene and of the corresponding hexagonal squeeze in this paper
