Let G = (V, E) be a simple graph of order n and the normalized Laplacian eigenvalues ρ1 ≥ ρ2 ≥ · · · ≥ ρn−1 ≥ ρn = 0. The normalized Laplacian energy (or Randić energy) of G without any isolated vertex is defined as 
Normalized Laplacian eigenvalues with chromatic number and independence number of graphs
ABSTRACT Let be the normalized Laplacian eigenvalues of a graph G with n vertices. Also, let χ and α be the chromatic number and the independence number of a graph G, respectively. In this paper, we
Spectral Gap of the Largest Eigenvalue of the Normalized Graph Laplacian
We offer a new method for proving that the maximal eigenvalue of the normalized graph Laplacian of a graph with $n$ vertices is at least $\frac{n+1}{n-1}$ provided the graph is not complete and that
Petals and Books: The largest Laplacian spectral gap from 1
We prove that, for any connected graph on N ≥ 3 vertices, the spectral gap from the value 1 with respect to the normalized Laplacian is at most 1 / 2. Moreover, we show that equality is achieved if
On the normalized Laplacian spectral radii of a graph and its line graph
TLDR
The extremal graph for the minimum normalized Laplacian spectral radii of nearly complete graphs is determined and several lower bounds are presented in terms of graph parameters and characterize the extremal graphs.
