Titel: Exponential renormalisation
Abstract: We look at Connes-Kreimer's Hopf algebra approach to renormalisation applying the so-called exponential method, to construct a character regular to all orders from an arbitrary character. The classical BPHZ method can be seen as a special case of this method for renormalization scheme maps with the Rota-Baxter property. This is based on joint work with F. Patras (CNRS).
