General Sum-Connectivity Index with a = 1 for Trees and Unicyclic Graphs with k Pendants

2015 17th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (SYNASC), 2015
One of the newest molecular descriptors, the general sum-connectivity index of a graph G is defined as ?a(G) = Suv?E(G)(d(u)+d(v))a, where d(u) denotes the degree of vertex u in G and a is a real number. The aim of this paper is to determine the trees and the unicyclic graphs with k pendant vertices that maximize the general sum-connectivity index for ...

General Randić and general sum connectivity indices of the conjugacy class graph

International Journal of Computer Mathematics Computer Systems Theory
For a real number α, $ R_{\alpha }(\Gamma ) = \sum _{h_{w}h_{x} \in E(\Gamma )}(deg(h_{w})deg(h_{x}))^{\alpha } $ Rα(Γ)=∑hwhx∈E(Γ)(deg(hw)deg(hx))α and $ \chi _{\alpha }(\Gamma ) = \sum _{h_{w}h_{x} \in E(\Gamma )} (deg(h_{w})+deg(h_{x}))^{\alpha } $ χα ...
