The lines sage: k.<n> = FunctionField(QQ) sage: R.<X> = k[] sage: l.<x> = k.extension(X^3+n-1) sage: E = EllipticCurve(l,[0,n]) sage: print 1 == x^3+n True
show that the point (x,1) lies on the elliptic curve E, which is defined over l too. However, E(x,1) fails with an intimidating traceback, with the last line being AttributeError: 'FunctionField_polymod_with_category' object has no attribute 'parent' Am I doing something wrong, or is there a bug in a very basic function? -- Peter Mueller -- You received this message because you are subscribed to the Google Groups "sage-support" group.
