Spectrum Analysis

Studying the spectrum of a topology, is an interesting and deep subject that reveals certain properties and sheds light to the particular of various network functions. For example, an analytical investigation of its spectral properties reveals that the minimum elements of its principal eigenvector correspond to the solution of the median problem.

The median matrix captures the median problem such that the smallest of principal eigenvector elements correspond to the solution of the problem.
