| Let $G$ be a graph with vertex set $V(G)$ and edge set $E(G)$, and let $d_u$ denote the degree of vertex $u$ in $G$. The Randi'c index of $G$ is defined as ${R}(G) =\sum_{uv\in E(G)} 1/\sqrt{d_ud_v}.$ In this paper, we investigate the relationships between Randi'c index and several topological indices. | ||
