For any undirected and weighted graph G=(V, E, w) with n vertices and m edges, we call a
sparse subgraph H of G, with proper reweighting of the edges, a (1+ ε)-spectral sparsifier if …

A sparse graph is one whose number of edges is reasonably viewed as being proportional
to the number of vertices. Since most algorithms run faster on sparse instances of graphs …
