Manifolds and Rotations have a name conflict on Rotations. Lets give Manifolds priority

This ticket proposes to change some methods that currently return lists to generators - like the method `open_supersets` added in #31677. This is in line with the changes in the Python standard libr…

We define a subclass of `ManifoldSubset` whose instances represents the topological closure of given subset in the manifold.
Subsets provide a method `closure` to construct it. When the subset is…

In the arithmetics of symbolic coordinate functions (methods `sage.manifolds.coord_func_symb.CoordFunctionSymb._add_`, `_sub_`, `_mul_` and `_div_`), the final result (`res` below) is checked agains…

We now have `rand` methods in Manifolds.jl so most (if not all) uses of `random_point` and `random_tangent` can be replaced by `rand` for more consistency. Eventually it would be nice to support custo…

If one uses the method `stereographic_coordinates` to initialize steographic coordinates (instead of as via the constructor argument), then there are some inconsistencies.
For example,
