Karl-Otto Stöhr

from Wikipedia, the free encyclopedia

Karl-Otto Stöhr (born May 9, 1942 in Koblenz ) is a German-Brazilian mathematician who is a professor in Rio de Janeiro at the Instituto de Matemática Pura e Aplicada (IMPA).

Life

Stöhr studied as a scholarship holder of the German National Academic Foundation at the University of Bonn with a diploma in 1966 and received his doctorate there in 1967 under Wolfgang Krull (and Jacques Tits ) in mathematics with the subject of homotopy theory of pro-algebraic groups and local class field theory . In addition to mathematics, he also studied physics (with Wolfgang Paul, among others ). Friedrich Hirzebruch and Jürgen Neukirch were also among his academic teachers . In 1969/70 he was an assistant professor at McGill University and then again in Bonn. Since 1972 he has been working and teaching at the IMPA in Rio de Janeiro.

Stöhr deals with algebraic geometry (as well as algebraic number theory and arithmetic of function fields). Among other things, he published on moduli of Gorenstein curves, Zeta functions and Poincaré series of singular algebraic curves, the Riemann hypothesis and rational points on projective curves, graining of singular curves in characteristic 1 and Weierstraß points and linear families on singular algebraic curves.

He is a member of the Brazilian Academy of Sciences and received the Ordem Nacional do Mérito Científico (1996). In 2002 he became a member of the European Academy of Sciences.

Arnaldo Garcia is one of his doctoral students .
