 Clifford–Klein form

The Clifford–Klein form refers to a particular representation of manifolds, especially in the context of Riemannian geometry. It is used to describe certain types of homogeneous spaces, which are spaces that exhibit uniformity in their geometric properties. ### Key Concepts: 1. **Homogeneous Spaces:** These are spaces where, at every point, there exists a symmetry which can take one point to another. Common examples include spheres and projective spaces.
