Erich Rothe

from Wikipedia, the free encyclopedia

Erich Hans Rothe (born July 21, 1895 in Berlin ; † February 19, 1988 ) was a German mathematician who worked in the field of analysis .

Life

Rothe was the son of a lawyer. After graduating from high school in 1913, Rothe studied mathematics for two semesters in Munich . He took part in the First World War as a war volunteer and was wounded. After the war, Rothe continued his mathematics studies at the TU Berlin in 1919 and then at the Friedrich-Wilhelms-Universität in Berlin, passed the teaching examination (mathematics, physics and philosophy, until 1926 trainee lawyer at the Mommsen-Gymnasium in Berlin-Charlottenburg) and received his doctorate 1927 with Erhard Schmidt and Richard von Mises ( About some analogies between linear partial and linear ordinary differential equations ). In 1928 he married the mathematician Hildegard Ille . From 1928 to 1931 he was a private lecturer and assistant to Fritz Noether at the Technical University of Breslau (habilitation there in 1928). He then was from 1931 to 1935 private lecturer at the University of Breslau (re- habilitation in 1931). After Rothe was dismissed from civil service due to his Jewish descent, he emigrated with his family to the USA in 1937. At William Penn College in Oskaloosa, Iowa, he and his wife taught from 1937. After the death of his wife, Erich Rothe became a lecturer ( assistant professor ) at the University of Michigan ( Ann Arbor ) in 1943 (1949 associate professor , 1955 full professor ). After retiring in 1964, Rothe taught for one year (1967/68) at Western Michigan University in Kalamazoo. In 1986 his book about the degree of mapping in Banach spaces was published . The Rothe method for handling partial differential equations is named after him. Also known is his theorem, proven in 1932, that a functional in a Hilbert space is weakly continuous if and only if its Fréchet derivative is complete .

Erich Rothe wrote more than 50 mathematical papers. His students included Jane Cronin Scanlon and George J. Minty .
