Project Description

Associated notebook file KateWishList.sws

Projects are listed by section below. No one is currently working on these ones:

• Compute lots of examples to find guesses for bounds on "C"
• Put Kate's EDS class into sage (document properly)?

Restricted global_minimal_model()

* Ticket needs review! #11827

Wrapping E.reduction(prime)(P)

* Our first positive review! #11822

p-adics

* Implement E.reduction(p) for E defined over a p-adic fields: reduction of elliptic curves over padics.sws

• This found a bug/needed enhancement which is now reported: #11826

* Tate's algorithm Tate.sws

Singular Cubics

Trac ticket 11823

* Currently the patch on the trac server will allow one to define singular cubics.

sage: E = WeierstrassCubic([0,0,0,0,0])
sage: E.is_singular()
True

* Stuff to do:

• Work through elliptic curve documentation, test functions that should work for singular curves, and update the following lists

• Document the WeierstrassCubic and SingularWeierstrass classes we've created

• Do the stuff on the list below
• make E.reduction(bad_prime) able to return this singular cubic object

• put the checks back in for EllipticCurve and SingularWeierstrass that it is actually (or is not) singular

* Functions that seem ok out of the box (so need only documentation adjustment/testing):

• a_invariants() etc
