We present a general framework for constructing cut sparsifiers in undirected graphs---weighted subgraphs for which every cut has the same weight as the original graph, up to a multiplicative factor of ( 1 ± ϵ). Using this framework, we simplify, unify, and improve upon previous sparsification results. citizens bank park concert
