It is not clear to me what ellperiods(e) returns when e is an ellinit for a curve defined over a number field. Also, if I want the period lattice for all the embeddings of the fields into R or C, how would I do that?
I am trying to see how many of the quantities appearing in the BSD conjecture can be computed in GP, over a number field. I am assuming that we know generators somehow (ellgenerators() is not available), and something to replace ellL1() so that we can get something like ellbsd().
I may have missed functions which are already there for curves over number fields -- if so, please tell me.
