Horst Knörrer (born 31 July 1953, in Bayreuth) is a German mathematician, who studies algebraic geometry and mathematical physics.
Knörrer studied from 1971 at University of Regensburg and University of Erlangen-Nuremberg and received a doctorate in 1978 from theUniversity of Bonn under the supervision of Egbert Brieskorn (Isolierte Singularitäten von Durchschnitten zweier Quadriken). After that, he was a research assistant until 1985 in Bonn, interrupted by two years 1980 to 1982 at theLeiden University. In 1985 he completed his habilitation in Bonn and was a Heisenberg fellow the following two years. During 1986/87, he was a department representative at the University of Düsseldorf. Since 1987, he is a full professor of mathematics at the ETH Zurich.
Knörrer studies algebraic geometry and its connection to mathematical physics, for example, for integrable systems, as well as mathematical theory of many-particle systems in statistical mechanics and solid state physics (Fermi liquids). Together with Brieskorn, he wrote an extensive and richillustrated textbook on algebraic curves, which also was translated into English.
