Ernst Peschl
Ernst Ferdinand Peschl (born September 1, 1906 in Passau ; † June 9, 1986 in Eitorf ) was a German mathematician.
Life
Ernst Peschl came from the family of a brewery owner. After attending the secondary school in Passau, he began studying mathematics, physics and astronomy in Munich in 1925. He received his doctorate in 1931 under Constantin Carathéodory at the University of Munich ( On the curvature of level curves in the conformal mapping of simply connected areas onto the interior of a circle; a generalization of a theorem by E. Study . ). This was followed by assistant years in Jena with Robert König and in Münster with Heinrich Behnke . During his studies he was a member of the SA for one year and then became a member of theNational Socialist German Lecturer Association . He completed his habilitation in Jena in 1935. After a substitute chair he became associate professor at the University of Bonn in 1938 . During the war he worked at the German Research Institute for Aviation in Braunschweig. After the war he became director of the Mathematical Institute in Bonn and in 1948 a full professor there. In Bonn he built the Institute for Pure and Applied Mathematics, the Institute for Instrumental Mathematics and the Society for Mathematics and Data Processing , which he led with Heinz Unger from 1969 to 1974.
Areas of work and effect
Ernst Peschl's main areas of work were geometric function theory , partial differential equations and the theory of the functions of several complex variables.
At Peschl, among others, Claus Müller , Friedhelm Erwe , Karl Wilhelm Bauer, Bernhard Korte , Stephan Ruscheweyh and Karl-Joachim Wirths received their doctorates.
Honors
Peschl received an honorary doctorate from the University of Toulouse in 1969 and an honorary doctorate from the University of Graz in 1982 . He was appointed Officier des Palmes Académiques by the French government in 1975 for his fruitful collaboration with French mathematicians . In 1983 he was awarded the Cross of Merit 1st Class of the Federal Republic of Germany.
Peschl was a full member of the North Rhine-Westphalian Academy of Sciences , the Bavarian and Austrian Academies of Sciences and a corresponding member of the Académie des Sciences, Inscriptions et Belles-Lettres de Toulouse . He received the Pierre Fermat Medal in 1965 and the Jyväskylä University medal .
