Oh, I knew FriCAS can already do it. ;-) The solution lies here.
If a: List(L) is the list elements from L that should be substituted for the variables, then something like this works. Q ==> Fraction Integer E ==> DirectProduct(#vl, NNI) GP ==> GeneralDistributedMultivariatePolynomial(vl, Q, E) OVL ==> OrderedVariableList vl fv(v: OVL): L == a lookup v LIFT ==> PolynomialCategoryLifting(E, OVL, Q, GP, L) If p: GP then evaluation is done like this. map(fv, x+->x, p)$LIFT Ralf -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
