{wiki=Cheeger_constant_(graph_theory)}
The Cheeger constant, also known as the Cheeger function or Cheeger number, is a concept from graph theory and geometric analysis that provides a measure of how "well-connected" a graph or a manifold is. In the context of a graph, the Cheeger constant is used to characterize the minimum cut that can be made to partition the graph into two disjoint sets.
