Hi, when I type example below... R.<x,y>=PolynomialRing(ZZ,2) I=R*(4*x^2*y^2+2*x*y^3+3*x*y,2*x^2+x*y,2*y^2) I.groebner_basis()
[x^2*y, x*y^2, 2*x^2 + x*y, 3*x*y, 2*y^2] ... this is wrong result. Right one is [x*y^3, 2*x^2 + x*y, 3*x*y, 2*y^2] (from the book, and calculating by hand). How can I find the bug? -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
