Friedrich Karl Schmidt

Friedrich Karl Schmidt ( born September 22, 1901 in Dusseldorf, † January 25, 1977 in Heidelberg ) was a German mathematician who worked primarily with algebra and number theory.

Life and work

Schmidt studied from 1920 to 1925 in Freiburg and Marburg. In 1925 he received his doctorate at the Albert- Ludwigs- University of Freiburg in Alfred Loewy on general body in the field of higher congruences. In 1927 he was a lecturer at the University of Erlangen, where he habilitated in 1933 and was an adjunct professor. 1933/34, he was a lecturer at the University of Göttingen, where he worked with Helmut Hasse, and then until 1946 a professor at the University of Jena. During the war years he was at the German Research Institute for Gliding in Reichenhall. After the war he became in 1946 professor at the Westfälische Wilhelms-Universität in Münster and from 1952 until his retirement in 1966 at the University of Heidelberg.

Schmidt was a member of the Heidelberg Academy of Sciences since 1954 and in 1968 honorary doctorate from the University of Berlin.

Schmidt is for function body (not only over the complex numbers, but also to other bodies), best known for his contributions to the theory of algebraic function fields, and in particular his definition of a zeta function for function fields and the proof of the Riemann -Roch theorem. In addition, he worked for class field theory and evaluation theory.

His doctoral include Reinhardt Kiehl, Ernst Kunz, Hans -Joachim Nastold and Chiungtze Tsen.
