Graph perturbations and corresponding spectral changes in Internet topologies
The physical meaning of the normalized Laplacian spectrum for the Internet. Graph perturbations and changes in the weighted spectral distribution. Graph perturbations and changes in the multiplicity of the eigenvalue 1. The two spectral metrics are asymptotically independent of network size. The two spectral metrics are a good choice for study on the Internet optimization.
