After 20 Years, Math Couple Solves Major Group Theory Problem | Quanta Magazine

Two mathematicians, Britta Späth and Marc Cabanes, solved the McKay conjecture after a 20-year effort, proving that properties of large mathematical groups can be understood by studying smaller subsets called Sylow normalizers. Their breakthrough work culminated in proving the conjecture for all finite groups, particularly completing the challenging case of Lie-type groups.
