I propose a patch (trac_13935_coercion_of_coproduct_of_Hopf_algebra-EliX-jbp.patch) to coerce elements like:
Let F[2,1,3] <http://trac.sagemath.org/sage_trac/log/?revs=1-3> be an element of the fundamental basis of the FreeQuasiSymmetric functions Hopf algebra (FQSym) and G an other basis. sage: G(F[2,1,3] <http://trac.sagemath.org/sage_trac/log/?revs=1-3> .coproduct()) G[] # G[2, 1, 3] + G[1] <http://trac.sagemath.org/sage_trac/changeset/1> # G[1, 2] + G[2, 1] # G[1] <http://trac.sagemath.org/sage_trac/changeset/1> + G[2, 1, 3] # G[] Some one may be must move my code (in Categories i think or anywhere)...
