Hans Grauert (born February 8, 1930 in Haren / Ems ; † September 4, 2011 in Göttingen ) was considered one of the most important German mathematicians of the post-war period. His specialty was the function theory of several variables.

life and work

Grauert attended high school in Meppen from 1946 to 1949 and studied (after a semester in Mainz , where he learned mathematical logic) from 1949 at the Westphalian Wilhelms University (WWU) in Münster with Heinrich Behnke , where he worked in 1954 with the work Kählersche Metrik in holomorphism , which was published two years later in the Mathematische Annalen . As a member of the Behnke School, he was able to benefit from the excellent contacts in France at the time, in particular with Henri Cartan . Before his dissertation he also studied in 1953 with the topologist Beno Eckmann at the ETH Zurich . In 1955 he became an assistant professor in Münster, where he completed his habilitation in 1957 before going to the Institute for Advanced Study for a year in 1957/58 . In 1959 he worked at the Institute des Hautes études Mathematiques (IHES) near Paris .

From September 1959 until his retirement he was full professor in Göttingen as the successor to Carl Ludwig Siegel . In Göttingen he formed a very active large school of complex analysis. He has also held visiting professorships, including in Princeton and Paris.

Together with Henri Cartan and Reinhold Remmert , a close collaborator since the 1950s, Grauert was the main engine of the boom that the complex analysis of several variables took after the Second World War .

In 1965 he gave another proof of the mordell presumption for functional bodies (originally proven by Yurij Manin ). In addition, he was busy u. a. with hyperbolic geometry and non-Archimedean function theory. Grauert also considered new geometric structures for use in physics ( Statistical geometry and spacetime , Comm. Math. Phys. Vol. 49, 1976, p. 155, and Nachr. Akad. Wiss. Göttingen 1976), as well as about the formalism of quantum theory.

From 1969 he was editor of the Mathematische Annalen . In 1966 he was invited speaker at the International Congress of Mathematicians in Moscow ( On non-Archimedean analysis , with Remmert) and in Edinburgh in 1958 ( The Riemann surfaces of the function theory of several variables ). In 1962 he gave a plenary lecture at the ICM in Stockholm ( The meaning of the Levi problem for analytical and algebraic geometry ).

His daughter Ulrike Peternell is also a mathematician, married to the mathematician Thomas Peternell , who did his doctorate under Grauert. Further doctoral students are Günther Trautmann , Klas Diederich (Wuppertal), Wolfgang Fischer (Bremen), Gudrun Kalmbach , Klaus Fritzsche , Ingo Lieb , Helmut Reckziegel (Cologne), Oswald Riemenschneider (Hamburg), Jürgen Spilker (Freiburg), Heinz Spindler (Osnabrück) .
