Bishop–Gromov inequality
On volumes in complete Riemannian n-manifolds whose Ricci curvature has a lower bound / From Wikipedia, the free encyclopedia
In mathematics, the Bishop–Gromov inequality is a comparison theorem in Riemannian geometry, named after Richard L. Bishop and Mikhail Gromov. It is closely related to Myers' theorem, and is the key point in the proof of Gromov's compactness theorem.[1]
