| Resumo | |
In this work we perform analytical and statistical studies of the Rodriguez-Velazquez (RV) indices on graphs G. The topological RV(G) indices, recently introduced in Rodriguez-Velazquez and Balaban (J Math Chem 57:1053, 2019), are based on graph adjacency matrix eigenvalues and eigenvectors. First, we analytically obtain new relations connecting RV(G) with the graph energy E(G) and the subgraph centrality EE(G), the later being proportional to the well known Estrada index. Then, within a random matrix theory (RMT) approach we statistically validate our relations on ensembles of randomly-weighted Erdos-Renyi graphs G(n, p), characterized by n vertices connected independently with probability p is an element of (0, 1). Additionally, we show that the ratio < RV(G(n, p))>/< RV(G(n, 0))> scales with the average degree < k > = (n - 1)p. (AU) | |
