7 | | Anyway, it would be good, at least for pedagogical purposes, that objects returned by `manifolds.Sphere(n)` come with a minimal atlas that covers the whole manifold, e.g. an atlas with the two stereographic charts. I understand that there is a performance issue for `n` large. To circumvent this, we could add an option like `complete_atlas=True`, so that if some user does not want to construct the stereographic charts and their transition map when initializing the manifold, he/she could set this option to `False`. |
