Sage Days 74: Differential geometry and topology

Sage Days 74 will take place on May 30 - June 2, 2016 at the Workshop Center (CIAS) of Observatoire de Paris, France.


Registration is now open. Contact Eric ([email protected]) and Travis ([email protected]) to register.




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

  • SageManifolds inclusion into Sage.

  • 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... what could be supported by a browser?







European participants from an OpenDreamKit node are expected to cover their expenses from their OpenDreamKit funds.
