Abstract

Let G be a simple connected graph in chemical graph theory and be an edge of G. The Randić index and sum-connectivity of a nontrivial connected graph G are defined as the sum of the weights and over all edges of G, respectively. In this paper, we compute Randić and sum-connectivity indices of V-phenylenic nanotubes and nanotori.
