Soit le groupe des échanges d’intervalles. Des résultats d’Arnoux–Fathi, Sah et Vorobets indiquent que le sous-groupe de engendré par ses commutateurs est simple. Arnoux prouve que le groupe des échanges d’intervalles avec flips est simple.
Nous établissons que tout élément de a une longueur des commutateur inférieure ou égale à . De plus, nous exhibons des conditions sur qui garantissent que les longueurs des commutateurs des éléments de sont uniformément bornées et dans ce cas pour tout nous montrons que cette longueur est au plus .
Let be the group of all Interval Exchange Transformations. Results of Arnoux–Fathi, Sah and Vorobets state that the subgroup of generated by its commutators is simple. Arnoux proved that the group of all Interval Exchange Transformations with flips is simple.
We establish that the commutator length is at most for any element of . Moreover, we give conditions on that guarantee that the commutator lengths of the elements of are uniformly bounded, and in this case for any this length is at most .
