[sage-support] Jacobian Element over HyperElliptic Curves

2009-10-28 Thread Daniel Ribeiro
Hi, I was doing some tests with the jacobian over HyperElliptic Curves, and I did not quite understand the output of __str__ method of the elements of such set. For instance: field = GF(2**5, 'a') a = field.gen() Px = PolynomialRing(field, 'x') x = Px.gen() f = x**5 + x**3 + 1 h = x**2 + x C =
