The physicist Hermann von Helmholtz assisted him in the work over night and returned with the comment that it was “natural” and “very understandable”.

Many mathematicians such as Alfred Clebsch furthered Riemann’s work on algebraic curves. Gotthold Eisenstein Moritz A. For other people with the surname, see Riemann surname. He made some famous contributions to modern analytic number theory. Kaluza—Klein theory Quantum gravity Supergravity.

Through his pioneering contributions to differential geometryRiemann laid the foundations of the mathematics of general relativity.
Although this attempt failed, it did result in Riemann finally being granted a regular salary.
Inat the age of 19, he started studying philology and Christian theology in order to become a pastor and help with his family’s finances. From those, some other global quantities can be derived by integrating local contributions. In his dissertation, he established a geometric foundation for complex analysis through Riemann surfacesthrough which multi-valued functions like the logarithm with infinitely many sheets or the square root with two sheets could become one-to-one functions.
DuringRiemann went to Hanover to live with his grandmother and attend lyceum middle school. The Riemann hypothesis was one of a series of conjectures he made about the function’s properties.

Two-dimensional Plane Area Polygon. He proved the functional equation for the zeta function already known to Leonhard Eulerbehind which a theta function lies. It deals with a broad range of geometries whose metric properties vary from point to point, including the standard types of Non-Euclidean geometry. Among other things, he showed that every piecewise continuous function is integrable. Retrieved 13 October Volume Cube cuboid Cylinder Pyramid Sphere.
The famous Riemann mapping theorem says that a simply connected domain in the complex plane is “biholomorphically equivalent” i. Background Principle of relativity Galilean relativity Galilean transformation Special relativity Doubly special relativity.

This page was last edited on 30 Decemberat Riemann had not noticed that his working assumption that the minimum existed might not work; the function space might not be complete, and therefore the existence of a minimum was not guaranteed. For the proof of the existence of functions on Riemann surfaces he used a minimality condition, which he called the Dirichlet principle. In high school, Riemann studied the Bible intensively, but he was often distracted by mathematics.
Riemann’s published works opened up research areas combining analysis with geometry. Square Rectangle Rhombus Rhomboid. His mother, Charlotte Ebell, died before her children had reached adulthood.
Light geometga World line Minkowski diagram Biquaternions Minkowski space. Complex functions are harmonic functions that is, they satisfy Laplace’s equation and thus the Cauchy—Riemann equations on these surfaces and are described by the location of their singularities and the topology of the surfaces.
Bernhard Riemann in Equivalence principle Riemannian geometry Penrose diagram Geodesics Mach’s principle. Riemann found the correct way to rienann into n dimensions the differential geometry of surfaces, which Gauss himself proved in his theorema egregium.
The subject founded by this work is Riemannian geometry. Brans—Dicke theory Kaluza—Klein Quantum gravity.
Any smooth manifold admits a Rimeann metricwhich often helps to solve problems of differential topology. InWeierstrass had taken Riemann’s dissertation with him on a holiday to Rigi and complained that it was hard to understand. This page was last edited on 30 Decemberat
