摘要：

Let G be a simple connected graph with the vertex set V(G) and the edge set E(G). The mconnectivity index (m)chi(a)(G) of an organic molecule whose molecular graph G is the sum of the weights (d(i1)d(i2) ... d(im+1))(alpha) where i(1), i(2), ..., i(m+1) runs over all paths of length m in G and d(i) is the degree of vertex v(i). In this paper, we compute the second-connectivity and second-sum-connectivity indices of TUC4C8(S) Nanotubes for the first time.
