*X*. This is a better parameter to measure the stability of a network

*G*, as it takes into account both the amount of work done to damage the network and how badly the network is damaged. In this paper, we give the exact values or bounds for...

_{α}(G) of a graph G=(V,E) is defined as Rα(G)=∑(u,v)∈E(G)(dudv)α, where (u, v) is an edge of G, d

_{u}and d

_{v}denote the degrees of the vertices u and v, respectively, and α ≠ 0 is an arbitrary real number. In this paper, we give the expressions for computing the general connectivity indices of fluoranthene-type benzenoid systems, and we determine the extremal values of R...
