Does Levy-Khinchine decomposition exists in the noncommutative framework ?

Résumé : Known since 1930ies, the Lévy-Khintchine formula provides a classification of Lévy processes on $\mathbb R^n$ in terms of their generators. It shows how the generators of Lévy processes are combinations of continuous (or Gaussian) parts and jump parts. In my talk I will discuss the problem of the existence of an analogous decomposition for Lévy processes’ generators on $*$-bialgebras and compact quantum groups, and comment on recent developments in this area.
