A. Alekseev, B. Enriquez, C. Torossian

摘要:

Kashiwara-Vergne(KV)猜想说明了与Campbell-Baker-Hausdorff级数相关的一对方程解的存在性。它是解决了迈伦肯和第一作者的实数,并在正式版本,由第一和最后一个作者在外地的特点0。本文给出了从Drinfeld结合子集到形式KV方程解集的映射的一个简单而显式的公式。这两个集合都是在prounipotent群作用下的torsors,我们证明了这个映射是torsors的态射。当专门的KZ结合子,我们的建设产生一个解决方案,在原来的KV猜想的实数。

英文摘要:

The Kashiwara-Vergne (KV) conjecture states the existence of solutions of a pair of equations related with the Campbell-Baker-Hausdorff series. It was solved by Meinrenken and the first author over the real numbers, and in a formal version, by the first and last authors over a field of characteristic 0. In this paper, we give a simple and explicit formula for a map from the set of Drinfeld associators to the set of solutions of the formal KV equations. Both sets are torsors under the actions of prounipotent groups, and we show that this map is a morphism of torsors. When specialized to the KZ associator, our construction yields a solution over the reals of the original KV conjecture.
