Mathematicians of the day. This is the famous Riemann hypothesis which remains today one of the most important of the unsolved problems of mathematics. Wikimedia Commons has media related to Bernhard Riemann. Dedekind writes in [3]: Riemann held his first lectures in , which founded the field of Riemannian geometry and thereby set the stage for Albert Einstein ‘s general theory of relativity.

He examined multi-valued functions as single valued over a special Riemann surface and solved general inversion problems which had been solved for elliptic integrals by Abel and Jacobi. For other people with the surname, see Riemann surname. Riemann found that in four spatial dimensions, one needs a collection of ten numbers at each point to describe the properties of a manifold , no matter how distorted it is. However he attended some mathematics lectures and asked his father if he could transfer to the faculty of philosophy so that he could study mathematics. Riemann’s idea was to introduce a collection of numbers at every point in space i. Prior to the appearance of his most recent work [ Theory of abelian functions ] , Riemann was almost unknown to mathematicians. He also proved the Riemann—Lebesgue lemma:

He had visited Dirichlet in Riemann refused to publish incomplete work, and some deep insights may have been lost forever. It was only published twelve years later in by Dedekind, two years after his death. Dirichlet loved to make things clear to himself in an intuitive substrate; along with this he would give acute, logical analyses of foundational questions and would avoid long computations as much as possible.

At this time a teacher from a local school named Schulz assisted in Bernhard’s education. Its early reception appears to have been slow but it is now recognized as one of the most important works in geometry.


Bernhard seems to have been a good, but not outstanding, pupil who worked hard at the classical subjects such as Hebrew and theology. He also worked with hypergeometric differential equations in using complex analytical methods and presented the solutions through the behavior of closed paths about singularities described by the monodromy matrix. Retrieved from ” https: Otherwise, Weierstrass was very impressed with Riemann, especially with his theory of abelian functions.

The Dirichlet Principle did not originate with Dirichlethowever, as GaussGreen and Thomson had all made use if it. The physicist Hermann von Helmholtz assisted him in the work over night and returned with the comment that it was “natural” and “very understandable”.

BreselenzKingdom of Hanover modern-day Germany. Views Read Edit View history. He had never had good health all his life and in fact his serious heath problems probably go back bbernhard further than this cold he caught.

Gustav Roch Eduard Selling. However, once there, he began studying mathematics under Carl Friedrich Gauss specifically his lectures on the method of least squares.

Bernhard Riemann

Riemann’s work always was based on intuitive reasoning which fell a little below the rigour required to make the conclusions watertight. We considered it our duty to turn the attention of the Academy to our colleague whom we recommend not as a young talent which gives great hope, but rather as a fully mature and independent investigator in our area of science, whose progress he in significant measure has promoted.

Gradually he overcame his natural shyness and established a rapport with his audience. In Bernhard entered directly into the third class at the Lyceum in Hannover.

Here, too, rigorous proofs were first given after the development of richer mathematical tools in this case, topology. Bernhard Riemann in Among Riemann’s audience, only Gauss was able to appreciate the depth of Riemann’s thoughts. Monastyrsky writes in [6]: Riemann studied the convergence of the series representation of the zeta function and found a functional equation for the disswrtation function.

In high disertation, Riemann studied the Bible intensively, but he was often distracted by mathematics. Riemann had been in a competition with Weierstrass since to solve the Jacobian inverse problems for abelian integrals, a generalization of elliptic integrals.

Georg Friedrich Bernhard Riemann

He showed a particular interest in mathematics and the director of the Gymnasium allowed Bernhard to study mathematics texts from his own library. They had one daughter. The work builds on Cauchy ‘s foundations of the theory of complex variables built up over many years and also on Puiseux ‘s ideas of branch points. 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.

The main purpose of the paper was to give estimates for the number of primes less than a given number.
