WebIn the rest of this section we shall prove the following relations between the eigenvalues of Mand certain purely combinatorial properties of G. Theorem 3 Let Gbe a d-regular undirected graph, and M = 1 d Abe its normal-ized adjacency matrix. Let 1 2 n be the real eigenvalues of M with multiplicities. Then 1. 1 = 1 and n 1. 2.

Web1 de mai. de 2024 · In this paper we investigate the relation between eigenvalue distribution and graph structure of two classes of graphs: the ( m, k) -stars and l-dependent graphs. We give conditions on the topology and edge weights in order to get values and multiplicities of Laplacian matrix eigenvalues. We prove that a vertex set reduction on … Web1 de jan. de 2006 · For a given graph, there is a natural question of the possible lists of multiplicities for the eigenvalues among the spectra of Hermitian matrices with that graph (no constraint is placed... in care of vs attention
