Hyperbolic volume

Hyperbolic volume typically refers to the volume of a three-dimensional hyperbolic manifold, which is a type of manifold that exhibits hyperbolic geometry. In hyperbolic geometry, the space is negatively curved, in contrast to Euclidean geometry, which is flat, and spherical geometry, which is positively curved. The concept of hyperbolic volume is most often studied in the context of three-dimensional hyperbolic manifolds.
