Baker{campbell{hausdorr Type Computations Using Noncommutative Symmetric Functions

Abstract

This paper presents some relations between noncommutative symmetric functions and free Lie algebras. We show in particular how to decompose a Lie projector of Solomon's descent algebra on Dynkin's and Klyachko's bases. We illustrate these methods on the example of the Hausdorr series.
