## Who is Bernhard Riemann?

(Show more) (Show more) Bernhard Riemann, in full Georg Friedrich Bernhard Riemann, (born September 17, 1826, Breselenz, Hanover [Germany]—died July 20, 1866, Selasca, Italy), German mathematician whose profound and novel approaches to the study of geometry laid the mathematical foundation for Albert Einstein ’s theory of relativity.

## What did Bernhard Riemann contribution to calculus?

Bernhard Riemann. Riemann also studied how functions compare with their trigonometric or Fourier series representation, which led him to refine ideas about discontinuous functions. He showed how complex function theory illuminates the study of minimal surfaces (surfaces of least area that span a given boundary).

**Was ist Thomas Riemann zu der herausragendsten Mathematiker?**

Trotz seines relativ kurzen Lebens wurde Riemann zu einem der herausragendsten Mathematiker, dessen Werk bis heute von großer Bedeutung für die Naturwissenschaften ist. Zum einen gehörte er zu den Begründern der Funktionentheorie, der Lehre von den Funktionen einer komplexen Veränderlichen.

### What did Riemann study in college?

During the spring of 1846, his father, after gathering enough money, sent Riemann to the University of Göttingen, where he planned to study towards a degree in theology. However, once there, he began studying mathematics under Carl Friedrich Gauss (specifically his lectures on the method of least squares).

### What is the contribution of Riemann in analysis?

In the field of real analysis, he is mostly known for the first rigorous formulation of the integral, the Riemann integral, and his work on Fourier series. His contributions to complex analysis include most notably the introduction of Riemann surfaces, breaking new ground in a natural, geometric treatment of complex analysis.

**What happened to Riemann’s parents?**

His father, Friedrich Bernhard Riemann, was a poor Lutheran pastor in Breselenz who fought in the Napoleonic Wars. His mother, Charlotte Ebell, died before her children had reached adulthood. Riemann was the second of six children, shy and suffering from numerous nervous breakdowns.

#### What does the Riemann–Roch theorem mean?

For example, the Riemann–Roch theorem (Roch was a student of Riemann) says something about the number of linearly independent differentials (with known conditions on the zeros and poles) of a Riemann surface.
