[Familles de Garside dans les monoïdes d'Artin–Tits et éléments bas d'un groupe de Coxeter]
Nous montrons que tout groupe d'Artin–Tits finiment engendré possède une famille de Garside finie, en introduisant la notion d'élément bas dans un groupe de Coxeter et en prouvant que, si
We show that every finitely generated Artin–Tits group admits a finite Garside family, by introducing the notion of a low element in a Coxeter group and proving that the family of all low elements in a Coxeter system
