For PHPTR Only Chapter 8 Spectra of Complex Networks 1. Explain why the spectrum of a graph is independent of vertex labeling. Answer: When we change the vertex labeling, i.e., when we permute the vertex labels, the new adja- cency matrix can be written in the form Anew = P?1AP, where P is a permutation matrix and A is old adjacency matrix. Therefore, the new adjacency matrix is similar to the old one. Hence, the eigenvalues of the matrix does not change. 2. Prove
