16009 Compute rank of elliptic curve defined over relative number field mmasdeu "Currently the following fails:
{{{
sage: x = QQ['x'].gen()
sage: F. = QuadraticField(5)
sage: K.** = F.extension(x^2-3)
sage: E = EllipticCurve(K,[0,0,0,b,1])
sage: E.rank()
}}}
This is because the sage function wrapping around Denis Simon's two-descent script does not consider relative number fields.
I propose an easy fix for it.
