This article contains a non-exhaustive list of coordinate charts for Riemannian manifolds and pseudo-Riemannian manifolds. Coordinate charts are mathematical objects of topological manifolds, and they have multiple applications in theoretical and applied mathematics. When a differentiable structure and a metric are defined, greater structure exists, and this allows the definition of constructs such as integration and geodesics.
Charts for Riemannian and pseudo-Riemannian surfaces
editThe following charts (with appropriate metric tensors) can be used in the stated classes of Riemannian and pseudo-Riemannian surfaces:
Surface Class | Surface | Charts |
---|---|---|
n-spheres | n-sphere Sn | Hopf chart |
Sphere S2 | Spherical coordinates
Stereographic chart Central projection chart Axial projection chart Mercator chart | |
3-sphere S3 | Polar chart | |
Euclidean spaces | n-dimensional Euclidean space En | Cartesian chart |
Euclidean plane E2 | Bipolar coordinates | |
Euclidean space E3 | Polar spherical chart
Prolate spheroidal chart (rational and trigonometric forms) Oblate spheroidal chart (rational and trigonometric forms) | |
Hyperbolic spaces | n-dimensional hyperbolic space Hn | Upper half-space chart (Poincaré model)

He settled down to work in a small desk in my room, filling out pages and more pages, which quickly exceeded the space available at the table, spreading through the floor. He performed long calculations in Monge charts and drew beautiful pictures.
