On the Spectrum of Laplacian Matrix
Let G be a simple graph of order n. The matrix ℒG=DG−AG is called the Laplacian matrix of G, where DG and AG denote the diagonal matrix of vertex degrees and the adjacency matrix of G, respectively. Let l1G, ln−1G be the largest eigenvalue, the second smallest eigenvalue of ℒG respectively, and λ1G...
