A simple characterization of special matchings in lower Bruhat intervals

Fabrizio Caselli, Mario Marietti

Published 2017-12-11Version 1

We give a simple characterization of special matchings in lower Bruhat intervals (that is, intervals starting from the identity element) of a Coxeter group. As a byproduct, we obtain some results on the action of special matchings.
