Bounds for the general sum-connectivity index of composite graphs

The general sum-connectivity index is a molecular descriptor defined as [Formula: see text] , where [Formula: see text] denotes the degree of a vertex [Formula: see text] , and α is a real number. Let X be a graph; then let [Formula: see text] be the graph obtained from X by adding a new vertex [For...
