Riemannian geometry – Wikipedia

This list is oriented to those who already know the basic definitions and want to know what these definitions are about. Dislocations and Disclinations produce torsions and curvature. Point Line segment ray Length. Any smooth manifold admits a Riemannian metricwhich often helps to solve problems of differential topology. Volume Cube cuboid Cylinder Pyramid Sphere.

In all of the following theorems we assume some local behavior of the space usually formulated using curvature assumption to derive geimetrie 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.

What follows is an incomplete list of the most classical theorems in Riemannian geometry. It deals with a broad range of geometries whose metric properties vary from point to point, including the standard types of Non-Euclidean geometry.

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 differentiable manifolds of higher dimensions. It is a very broad and abstract generalization of the differential geometre of surfaces in R 3.

Principle of relativity Galilean relativity Galilean transformation Special relativity Doubly special relativity. Elliptic geometry is also sometimes called “Riemannian geometry”. Riemannian geometry originated with the vision of Bernhard Riemann expressed in his inaugural lecture ” Ueber die Hypothesen, welche der Geometrie zu Grunde liegen ” “On the Hypotheses on which Geometry is Based”. Riemannian geometry was first put forward in generality by Bernhard Riemann in the 19th century.

It enabled 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.

Geometriie geometry is the branch of differential geometry that studies Riemannian manifoldssmooth manifolds with a Riemannian metrici. This gives, in particular, local notions of anglelength of curvessurface area and volume.
