Webthe analysis of graphs will be the spectrum—i.e., the set of eigenvalues—of the graph’s adjacency matrix. The spectrum of the graph’s adjacency matrix is also called the spectrum of the graph. 2. Applying the semicircle law for the spectrum of the uncorrelated random graph A general form of the semicircle law for real symmetric Webthe number of links grows as the number of nodes, the spectral density of uncorrelated random matrices does not converge to the semicircle law. Furthermore, the spectra of real-world graphs have specific features, depending on the details of the corresponding models. In particular, scale-free graphs develop a trianglelike spectral density with ...
