Resumen:
We study the properties of eigenvalues and eigenvectors of the Google matrix of the Wikipediaarticles hyperlink network and other real networks. With the help of the Arnoldi method, we analyzethe distribution of eigenvalues in the complex plane and show that eigenstates with significant eigenvaluemodulus are located on well defined network communities. We also show that the correlator betweenPageRank and CheiRank vectors distinguishes different organizations of information flow on BBC and LeMonde web sites.
