Symmetril Moulds, Generic Group Schemes, Resummation of Mzvs
  The present article deals with various generating series and group schemes (not necessarily affine ones) associated with MZVs. Our developments are motivated by Ecalle's mould calculus approach to the latter. We propose in particular a Hopf algebra--type encoding of symmetril moulds and introduce a new resummation process for MZVs.
