Projects

Here is a list of possible projects. Feel free to add your own to the list.

  • SageManifolds inclusion into Sage (cf. #18528)

  • Lie algebras #14901 and implement their relationship with manifolds.

  • CW/Cube complexes by generalizing the manifold classes.
  • Computation of geodesics on pseudo-Riemannian manifolds.
  • Include the sage.geometry.riemannian_manifolds (i.e. parametrized surfaces) into the more general framework of SageManifolds.

  • Experiment plotting possibilities with OpenGL (nice stuff from SnapPy!) and more... for rendering in browser there is the WebGL javascript library that is supported by most browsers.

  • Improve persistent homology.
  • Simplicial sets. (Co)simplicial objects in various categories.
  • Incorporation of Kenzo?

  • Improve/Implement knot theory in Sage (cf. #17030 #20509)

  • Implement more (co)homology theories (e.g., De Rham cohomology).
  • Implement methods for computing homotopy groups.
  • Tropical curves/geometry.
  • Implement Lie groups and related geometric objects such as Schubert cells.
  • Implement geometric crystals.
  • Implement hyperbolic space for dimensions > 2.

  • Implement common metric spaces; for example, Lp spaces.

  • Combine/standardize features of the hyperbolic plane with SageManifolds.

  • Sage development workflow (cf. https://wiki.sagemath.org/CodeSharingWorkflow)

Details

Lodging

We recommend to book a room in some hotel in Paris, in Montparnasse area (14th arrondissement). In particular, we recommend the

Other hotels are

If you prefer to stay in Meudon, at a walking distance (25 min) from the Workshop Center (CIAS), see

For a larger choice, see this list of convenient hotels from LESIA/Observatoire de Paris.

NB: since May/June is a high touristic season in Paris, it is recommended to book a room as soon as possible!

Transportation

Meudon is located at 10 min by train from Montparnasse station in Paris. All hotels listed above are located at a walking distance from Montparnasse station. A system of car shuttle will be organized from Meudon station to the Workshop Center (CIAS).

If you plan instead to come by your own, please follow these access instructions (click on the map to enlarge it; the CIAS is located in BAT. 9).

More details soon...

Funding

European participants receiving some OpenDreamKit funding for conferences/workshops are expected to use it to cover their expenses.
