Remarks on Bounds of Normalized Laplacian Eigenvalues of Graphs

Let $G$ be a connected undirected graph with $n$, $n\ge 3$, vertices and $m$ edges. Denote by $ρ_1 \ge ρ_2 \ge \cdots > ρ_n =0$ the normalized Laplacian eigenvalues of $G$. Upper and lower bounds of $ρ_i$, $i=1,2,\ldots , n-1$, are determined in terms of $n$ and general Randi\' c index, $R_{-1}$.
