Gottfried Köthe
Gottfried Maria Hugo Köthe (born December 25, 1905 in Graz , † April 30, 1989 in Frankfurt am Main ) was an Austrian mathematician who dealt with functional analysis and algebra .
Live and act
Gottfried Köthe studied mathematics, physics, chemistry and philosophy in Graz (and one semester in Innsbruck) from 1923 to 1927. In 1927 he received his doctorate in Graz under Anton Rella ( contributions to Finsler's foundation of set theory ) and then studied with Paul Finsler , Karl Rudolf Fueter and Andreas Speiser in Zurich , with Emmy Noether in Göttingen (1928/9) and Felix Hausdorff and Otto Toeplitz in Bonn (whose assistant he was). In 1931 he completed his habilitation and became a private lecturer in Münster with Heinrich Behnke and in 1937 an associate professor. In 1941 he became associate professor and in 1943 professor in Giessen . Afterwards he was professor in Mainz from 1946 (he was head of the mathematical institute there and from 1954 to 1956 rector), from 1957 professor for applied mathematics in Heidelberg (where he was rector 1960/1) and from 1965 in Frankfurt am Main, where he retired in 1971.
Köthe became known for his investigations into linear topological vector spaces. In the 1930s he and Toeplitz investigated sequential spaces and especially perfect spaces , which Jean Dieudonné recognized in 1942 as special cases of the theory of locally convex spaces . His book "Topological Linear Spaces" from 1960 became a standard work. He also dealt with the theory of algebras and rings and lattice theory .
In 1962 he received the Palmes Academiques. In 1963 he received the Gauss Medal in Braunschweig. He was a member of the Academy of Sciences Leopoldina , the Braunschweig Scientific Society and the Heidelberg Academy of Sciences . Köthe was an honorary doctor from the universities of Montpellier, Münster, Mainz, and Saarbrücken. In 1958 he was President of the German Mathematicians Association .
He was invited speaker at the International Congress of Mathematicians in Bologna in 1928 (structure of the rings that meet the average minimum condition), in Zurich in 1932 (maximum systems of infinite matrices, with Otto Toeplitz) and in Oslo in 1936 (on the solution of equations with infinitely many unknowns in topological spaces).
His estate is kept by the Central Archives of German Mathematicians' bequests at the Lower Saxony State and University Library in Göttingen .
