LocSol(Aly) *needs testing and debugging Independent(Jen) *needs is_linear_independent method on elliptic curves (mwrank from number field to function field--ask Cremona?) *this is dependent on heights PointSearchFF *immediate goal is height zero and one cases QuartMin(Gerriet) ([[attachment:quartmin_ff.sage|current implementation]]) *finished but not tested *UPDATE (6/4): When Kevin and Jen were trying to put everything together, they noticed that this file actually isn't used in DAR's original code. Turns out, if you read his thesis closely, it should in fact *never* be used. So nothing's wrong with his algorithm, we just have an extra file. Kevin and Jen are now discontinuing work on this file. Other *Need to put the following functions into ell_function_field: ** gens() ** rank() ** torsion_subgroup() (need Mazur's theorem!!!!) Typos in Examples *compile and fix these * p. 34: (3.15) T+36 should be T+56 * p. 35: should be (d_1, d_2) = ((T+17)(T+25),1) (not (T+17)(T+35)) * p. 35: should be (1) (T+17)(T+25)Z,,1,,^2^ - Z,,2,,^2^ + ... * p. 35: should be (2) (T+17)(T+25)Z,,1,,^2^ - (T+17)(T+25)Z,,3,,^2^ + ... Comments: * p. 34: quadric intersection in (3.16) depends on the labeling of two torsion as in (3.14). See TD_full comment at the top of the code.
