On Drinfel'd associators
Résumé
In 1986, in order to study the linear representations of the braid group $B_n$
coming from the monodromy of the Knizhnik-Zamolodchikov differential equations,
Drinfel'd introduced a class of formal power series $\Phi$
on noncommutative variables. These formal series can be considered as a class of associators.
We here give an interpretation of them as well as some new tools over Noncommutative Evolution
Equations. Asymptotic phenomena are also discussed.
