Twisted Lie algebras and idempotent of Dynkin.

Sémin. Lothar. Comb. 62, B62b, 22 p., electronic only (2009)


Summary: In this paper we define a Dynkin idempotent for twisted Hopf algebras and generalize the results of Patras and Reutenauer in the classical case. We treat as a special case the free Lie algebra and so generalize the results of Waldenfels.
