A one-parameter deformation of the noncommutative Lagrange inversion formula
Résumé
We give a one-parameter deformation of the noncommutative Lagrange inversion formula, more precisely, of the formula of Brouder-Frabetti-Krattenthaler for the antipode of the noncommutative Fa ́ di Bruno algebra. Namely, we obtain a closed for- a mula for the antipode of the one-parameter deformation of this Hopf algebra discovered by Foissy.
