11 Feb 2010 | | Abstract: | We prove an estimate on denominators of rational Drinfeld associators. To
obtain this result, we prove the corresponding estimate for the p-adic
associators stable under the action of suitable elements of Gal(ar{Q}/Q). As
an application, we settle in the positive Duflo’s question on the
Kashiwara--Vergne factorizations of the Jacobson element
J_p(x,y)=(x+y)^p-x^p-y^p in the free Lie algebra over a field of characteristic
