Workshop on Algorithms in Number Theory and Arithmetic Geometry
This wiki is intended for projects related to SageMath during the workshop Algorithms in Number Theory and Arithmetic Geometry (Leiden, 31 July-4 August 2017).

CoCalc project for discussion/coding sessions (not necessarily SageMath-related): https://cocalc.com/projects/24e6bfa2-6cc4-425e-95e4-7a2c92ce446f/ (please send an e-mail to P.J.Bruin@math.leidenuniv.nl to be added to this project)

SageMath 8.0 has now sage.schemes.riemann_surfaces.riemann_surface.RiemannSurface for numerical computation of period matrices. See August 1 presentation RiemannMatrixPresentation.ipynb. Perhaps this is more easily viewed via the (slightly broken) https://nbviewer.jupyter.org/url/www.cecm.sfu.ca/%7Enbruin/Leiden_presentation.ipynb. Integrate this code better into the rest of sage, e.g.:
- put a method on plane algebraic curves to get the corresponding Riemann surface?
- Improve the Gauss-Legendre integrator to compute the integration nodes in a more efficient way?
There is already code to compute a
Z -basis for the endomorphism ring numerically. Perhaps support computations of isogenies as well?- Make the Rosati involution available?
