Dear Jim, The problem is that kQ.gens()[0] is not an element of the kQ.monoid() as is required as said in the documentation and the examples. To fix your problem:
sage: kQ = FreeAlgebra(QQ ,2 , 'x') sage: gens=kQ.monoid().gens() sage: mons = [gens[0], gens[1], gens[0]*gens[1]] sage: mats = [Matrix(QQ,3,[1, 0, 0, 0, 1, 0, 0, 0, 0]), Matrix(QQ, 3, [0, 0, ....: 0, 0, 0, 0, 0, 0, 1])] sage: A = FreeAlgebraQuotient(kQ, mons, mats, 'x') sage: A.gens()[0]*A.gens()[1] 0 -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
