Martin Kneser (* 21. Januar 1928 in Greifswald; † 16. Februar 2004 in Göttingen) war ein deutscher Mathematiker, der sich mit Algebra (speziell quadratischen Formen) beschäftigte. (de) Martin Kneser (21 janvier 1928 – 16 février 2004 à Göttingen) est un mathématicien allemand qui a travaillé en algèbre, en particulier sur les formes quadratiques et les groupes algébriques. (fr) Martin Kneser (21 January 1928 – 16 February 2004) was a German mathematician. His father Hellmuth Kneser and grandfather Adolf Kneser were also mathematicians. He obtained his PhD in 1950 from Humboldt University of Berlin with the dissertation: Über den Rand von Parallelkörpern. His advisor was Erhard Schmidt. His name has been given to Kneser graphs which he studied in 1955. He also gave a simplified proof of the Fundamental theorem of algebra. Kneser was an Invited Speaker of the ICM in 1962 at Stockholm. His main publications were on quadratic forms and algebraic groups.
