The Rise-Contact involution on Tamari intervals
Résumé
We describe an involution on Tamari intervals and m-Tamari intervals. This involution switches two sets of statistics known as the "rises" and the "contacts" and so proves an open conjecture from Préville-Ratelle on intervals of the m-Tamari lattice.
