Core percolation in random graphs: a critical phenomena analysis
We show in particular in section 6.1 that for any α the core of a random graph only carries a small number of 0 eigenvalues of the adjacency matrix and that the emergence of the core has a direct impact on the localized and delocalized eigenvectors with eigenvalue 0.
Core percolation in random graphs: a critical phenomena analysis
We denote the number of points in the core by Nc and the number of edges in the core by Lc .
Core percolation in random graphs: a critical phenomena analysis
Remember that by definition, the number of isolated points after leaf removal is N i(α) + o(N ), the number of vertices in the core is Nc = N c(α) + o(N ), and the number of edges in the core is Lc = N l(α) + o(N ).
Core percolation in random graphs: a critical phenomena analysis
The fact that the core of a graph is an induced subgraph of the original graph allows to give a physicist’s argument for the uniqueness of the giant component in the core.
