  • For a simple finite graph G, general sum-connectivity index is defined for any real number α as χα(G) =  , which generalises both the first Zagreb index and the ordinary sum-connectivity index. In this paper, we present some new bounds for the general sum-connectivity index. We also present relation between general sum-connectivity index and general Randić index.
