#5890: clean up schemes/elliptic_curves/ell_generic.py
---------------------------+------------------------------------------------
Reporter: AlexGhitza | Owner: was
Type: defect | Status: new
Priority: major | Milestone: sage-4.0
Component: number theory | Keywords: elliptic curve field
---------------------------+------------------------------------------------
As noted at #5765, {{{ell_generic.py}}} has some functions that do not
make sense over a general ring and should rather be moved down to
{{{ell_field.py}}} or one of its descendants.
Note also William's comment from #5765: I think it would be nice to be
able to implement the elliptic curve factorization method (ECM) without
having to use this hack:
{{{
R = Zmod(N)
R.is_field = lambda: True
E = EllipticCurve(R, [-1,0])
}}}
