Other generalizations of Riemannian geometry include Finsler geometry. There exists a close analogy of differential geometry with the mathematical structure of defects in regular crystals. Elliptic geometry is also sometimes called “Riemannian geometry”.
Equivalence principle Riemannian geometry Penrose diagram Geodesics Mach’s principle. Most of the results can be found in the classic monograph by Jeff Cheeger and D. Development of Riemannian geometry resulted in synthesis of diverse results concerning the geometry of surfaces and the behavior of geodesics on them, with techniques that can be applied to the study of gometrie manifolds of higher dimensions.

It deals with a broad range of riemanniwnne whose metric properties vary from point to point, including the standard types of Non-Euclidean geometry.
Retrieved riemmannienne ” https: Riemannian geometry was first put forward in generality by Bernhard Riemann in the 19th century. What follows is an incomplete list of the most classical theorems in Riemannian geometrei. The choice is made depending on its importance and elegance of formulation. It geomtrie the formulation of Einstein ‘s general theory of relativitymade profound impact on group theory and representation theoryas well as analysisand spurred the development of algebraic and differential topology.

In all of the following theorems we assume some local behavior of the space usually formulated using curvature assumption to derive some information about the global structure of the space, including either some information on the topological type of the manifold or on the behavior of points at “sufficiently large” distances. This list is oriented to those who already know the basic definitions and want to know what these definitions are about.
