       Returns the period lattice of the elliptic curve.

       elliptic curve (with respect to the natural embedding of QQ into
       RR).

The documentation speaks of ""the"" period lattice of E, but to define a period lattice one needs an invariant differential as well.  From the documentation, it is not clear to me which differential is chosen here.",defect,closed,minor,sage-4.8,elliptic curves,fixed,,,,N/A,John Cremona,Johan Bosman,sage-4.8.alpha5,,
