# RIEMANN 1854 HABILITATION DISSERTATION

Many mathematicians such as Alfred Clebsch furthered Riemann’s work on algebraic curves. In , Gauss asked his student Riemann to prepare a Habilitationsschrift on the foundations of geometry. Riemann found the correct way to extend into n dimensions the differential geometry of surfaces, which Gauss himself proved in his theorema egregium. This is the famous Riemann hypothesis which remains today one of the most important of the unsolved problems of mathematics. Riemann was bound to Dirichlet by the strong inner sympathy of a like mode of thought. While preceding papers have shown that if a function possesses such and such a property, then it can be represented by a Fourier series , we pose the reverse question: It possesses shortest lines, now called geodesics, which resemble ordinary straight lines.

Riemann used theta functions in several variables and reduced the problem to the determination of the zeros of these theta functions. 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. In a letter to his father, Riemann recalled, among other things, “the fact that I spoke at a scientific meeting was useful for my lectures”. His mother, Charlotte Ebell, died before her children had reached adulthood. It is a beautiful book, and it would be interesting to know how it was received. He made some famous contributions to modern analytic number theory.

Prior to the appearance of his most recent work [ Theory of abelian functions ]Riemann was almost unknown to mathematicians. He managed to do this during 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. We considered it our duty to turn the attention of the Academy to our colleague whom we recommend not as a young talent riemajn 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.

Riemann was a dedicated Christian, the son of a Protestant minister, and saw his life as a mathematician as another way to serve God.

Dirichlet has shown this for continuous, piecewise-differentiable functions thus with countably many non-differentiable points. According to Detlef Laugwitz[11] automorphic functions appeared for dissertatuon first time in an essay about the Laplace equation on electrically charged cylinders.

Riemann’s published works opened up research areas combining analysis with geometry. One-dimensional Line segment ray Length. A few days later he was elected to the Berlin Academy of Sciences. Finally let us return to Weierstrass ‘s criticism of Riemann’s use of the Dirichlet ‘s Principle.

Riemann’s thesis, one of the most remarkable pieces of original work to appear in a doctoral thesis, was examined on 16 December Gauss recommended that Riemann give up his theological work and enter the mathematical field; after getting his father’s approval, Riemann transferred to the University of Berlin dissertatjon Riemann had been in a competition with Weierstrass since to solve the Jacobian inverse problems for abelian integrals, a generalization of elliptic integrals.

He made some famous contributions to modern analytic number theory. Kleinhowever, was fascinated by Riemann’s geometric approach and he wrote a book in giving his version of Riemann’s work yet written very much in the spirit of Riemann. Riemann found the correct way to extend into n dimensions the differential geometry of surfaces, which Gauss himself proved in his theorema egregium.

Riemann refused to publish incomplete work, and some deep insights may have been lost forever.

The Riemann hypothesis was one of a series of conjectures he made about the function’s properties. In the first part he posed the problem of how to define an n-dimensional space and ended up giving a definition of what today we call a Riemannian space.

Through his pioneering contributions to differential geometryRiemann laid the foundations of the mathematics of general relativity. It contained so many unexpected, new concepts that Weierstrass withdrew his paper and in fact published no more. His contributions to complex analysis include most notably the introduction of Riemann surfacesbreaking new ground in a natural, geometric treatment of complex analysis.

Bernhard seems to have been a good, but not outstanding, pupil who worked hard at the classical subjects such as Hebrew and theology. This circumstance excuses somewhat the necessity of a more detailed examination of his works as a basis diseertation our presentation.

The majority of mathematicians turned away from Riemann Rieemann 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.
