Bornhard Riemann

Georg Friedrich Bernhard Riemann (German: Georg Friedrich Bernhard Riemann, September 17, 1826 - July 20, 1866), a German mathematician, the proposer of Riemannian geometry, the Riemann Hypothesis, and one of the founders of complex variable function theory. He made outstanding contributions in the fields of mathematical analysis, number theory, differential geometry, and is widely regarded as one of the greatest mathematicians in history. Starting from the convergence of trigonometric series, Riemann proposed the Riemann integrability theory. His research on the distribution of prime numbers also laid the foundation for the discipline of analytic number theory. Riemann introduced concepts such as Riemann surfaces and Riemannian manifolds for the first time, opening up the development path of topology and differential geometry. The Riemannian geometry he established provided mathematical tools for general relativity.
