Hyperbolic space
HOMOGENEOUS SPACE THAT HAS A CONSTANT NEGATIVE CURVATURE (NOT ANY HYPERBOLIC MANIFOLD)
Hyperbolic 3-space; Real hyperbolic space; Hyperbolic Space; Hyperbolic spaces; Hyperbolic Spaces; H^n
In mathematics, hyperbolic space of dimension n is the unique simply connected, n-dimensional Riemannian manifold of constant sectional curvature equal to -1. It is homogeneous, and satisfies the stronger property of being a symmetric space.
