WebAbstract. We prove that every graph has a spectral sparsifier with a number of edges linear in its number of vertices. As linear-sized spectral sparsifiers of complete graphs are expanders, our sparsifiers of arbitrary graphs can be viewed as generalizations of expander graphs. In particular, we prove that for every d > 1 and every undirected ... WebIn fact, the complete graph has much better spectral sparsifiers. Consider the Ramanujan graphs, 26, 27 which are d-regular graphs all of whose non-zero Laplacian eigenvalues lie between d 2 and d + 2. ... Twice-Ramanujan sparsifiers. In a nutshell, Spielman and Srivastava first reduced the sparsification of G = ...
