[sage-devel] Re: GSoC projects
I think it would make more sense to wrap qepcad than to rewrite its functionality from scratch. Of course, SymPy doesn't follow the same approach as Sage, so i guess for them it makes sense to reinvent the wheel.

In general, based on the experience from the last years: If such a FLINT or Pari related project is of interest (i.e. there is at least one mentor for the theoretical aspects) there needs to be at least one mentor from the respective project (technical aspect, community interaction). If that is given, this could be a great project. Harald -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

It's available in Sage, by the way some tickets enhancing the interface or related functions need review: #15148 and #11980. To circumvent the liumiataion of Harvey's algorithm, we would need an implementation of the plain Kedlaya algorithm and the char 2 variation by Denef Vercauteren. For non-prime field with moderate characteristic, we would also need some method using deformation theory.

Re: [sage-devel] Re: GSoC projects
1. We use pari's SEA for elliptic curves over prime fields. the next version of pari, 2.7, is supposed to have point-counting over non-prime fields. 2. There is also very good code out there for hyperelliptics, I think by Sutherland. Do you need more general curves than that?
