Combinatorial study of colored Hurwitz polyz\^etas
  A combinatorial study discloses two surjective morphisms between generalized shuffle algebras and algebras generated by the colored Hurwitz polyz\^etas. The combinatorial aspects of the products and co-products involved in these algebras will be examined.
