  • The concept of general sum connectivity index was introduced in the area of chemical graph theory recently. Several of its particular cases have proven to correlate well with physical and chemical properties of some molecules. The main aim of this paper is to obtain new inequalities relating the general sum connectivity indices of a graph and its line graph.
