Reflections and quotients in Coxeter groups
Year: 2025
Type: article
Abstract: We present a formula relating the set of left descents of an element of a Coxeter group with the sets of left descents of its projections on maximal quotients indexed by simple right descents. This formula is an instance of a general result involving quotients and descents.
