+Title: Le s-Ordre faible et s-Permutaèdre
+date: 2023-12-14 00:10
+slug: 2023-12-14-s-weak-order
+lang: fr
+location: IHP, Paris
+slides: 2023_IHP.pdf
+conference_name: Séminaire francilien de géométrie algorithmique et combinatoire
+tags: S-weak-order, s-permutohedra, Tamari, Séminaire
+
+Le permutaèdre et le treillis associé de l'ordre faible sur les permutations sont des objets classiques de la combinatoire et géométrie discète. En particulier, les liens géométriques et combinatoires avec l'associaèdre et le treillis de Tamari font l'objet de nombreux travaux. Nous présentons une généralisation de l'ordre faible, le s-ordre faible sur une certaine famille d'arbres et discutons du s-Permutaèdre associé et de sa réalisation possible comme complexe polytopal. En collaboration avec Cesar Ceballos.
