Expander Decomposition

Type: Concept

As of November 2026, Expander Decomposition has been mentioned in one podcast episode on Institute for Advanced Study (Jan 2026). Mentioned as a technique for structural analysis in graph algorithms.

In graph theory, an expander graph is a sparse graph that has strong connectivity properties, quantified using vertex, edge or spectral expansion. Expander constructions have spawned research in pure and applied mathematics, with several applications to complexity theory, design of robust computer networks, and the theory of error-correcting codes.
