#4453: elliptic curves -- heegner_index command gives nonsense when rank > 1
---------------------------+------------------------------------------------
Reporter: was | Owner: was
Type: defect | Status: new
Priority: minor | Milestone: sage-3.2
Component: number theory | Keywords:
---------------------------+------------------------------------------------
For any elliptic curve over QQ of rank >= 2 the heegner_index command must
always give 0 as output. So the following 1 at the end is just wrong.
{{{
sage: E = EllipticCurve('389a')
sage: D = E.heegner_discriminants_list(1)[0]
sage: D
-7
sage: E.heegner_index(D)
1
}}}
