Query: Wave-Function renormalization and the Hopf algebra of Connes and Kreimer   In this talk, we show how the Connes-Kreimer Hopf algebra morphism can be
extended when taking into account the wave-function renormalization. This leads
us to a semi-direct product of invertible power series by formal
diffeomorphisms.
