Thanks Travis for handling the process again. I will not have time myself for GSOC this year. But I would like to enhance Michael proposal (if there is a strong enough candidate) :
* flint has two implementations of qqbar : one working with "multivariate ideals" and one working with "univariate minimal polynomials". Depending on the usage, one is more suited than the other. It is not clear how to interface both in sage (the drop in for AA/QQbar replacement would be the former for sure). * the former calcium is much more than algebraic numbers as it can handle things like sqrt(exp(2) + sqrt(5)). I think that if the project goes well there could be a SymbolicRealField/SymbolicComplexField on top of calcium Best Vincent On Tue, 3 Mar 2026 at 02:27, Michael Orlitzky <[email protected]> wrote: > > On 2026-03-01 18:23:32, Travis Scrimshaw wrote: > > > > Another thing that is good to have is more ideas, they can be things you > > (or a colleague) want implemented, something somewhat larger you want to be > > improved, or just some wishlist item you're not even sure how to do (yet). > > If you have such ideas, please also either post them here or add them to > > the GSoC ideas page: https://wiki.sagemath.org/GSoC/2026 > > A relatively straightforward but still large-enough project would be > to create a replacement for AA and QQbar within Sage based on Fredrik > Johansson's Calcium library.
