Robert, You have been answered how to solve the problem. But I would like to remark Volker's advice.
Do not use ideals over CC. CC is an inexact ring, so most operations will fail. Work instead over the rationals. R.<x,y> = PolynomialRing(QQ,2) or if you need complex numbers, you may try with a number field N.<I> = NumberField(x^2+1) R.<x,y> = PolynomialRing(N, 2) -- 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
