A two-parameter deformation of the quasi-shuffle\\ and new bases of quasi-symmetric functions

Résumé

We define a two-parameter deformation of the quasi-shuffle by means of the formal group law associated with the exponential generating function of the homogeneous Eulerian polynomials, and construct bases of $QSym$ and $\WQSym$ whose product rule is given by this operation.
