Werner Wolfgang Rogosinski

from Wikipedia, the free encyclopedia

Werner Wolfgang Rogosinski (born September 24, 1894 in Breslau ; † July 23, 1964 in Aarhus ) was a German-British mathematician .

Werner Rogosinski, Göttingen 1920


The father, Hermann Rogosinski, was a counselor in Breslau. From 1900 to high school in 1913, Werner Wolfgang Rogosinski attended the humanistic Maria Magdalenen grammar school in his hometown. He then studied at the universities in Breslau , Freiburg and, most recently, in Göttingen under Edmund Landau . The studies were interrupted by the First World War , in which Rogosinski was used as a medic . He concentrated his studies on pure mathematics ( theoretical mathematics ), in addition, he had studied physics and philosophy . He was interested in analytical problems, especially ranks . With his dissertation, New Application of Pfeiffer's Method in Dirichlet's divider problem , which he wrote in just two weeks , he caused a sensation in the mathematical world in 1922, into which he self-confidently grew with this success. Rogosinski married his sister's childhood friend in Königsberg in 1928 . In 1932 their son Peter was born. The mathematician, who comes from Germany, was also characterized by his English friends as "cozy".


In 1923 Rogosinski went to Königsberg , first as a private lecturer and from 1928 as an associate professor. This was followed by five productive and successful years working with Richard Brauer , Gabor Szegö and Kurt Reidemeister . The Rogosinski and Szegö families became friends. Rogosinski published his first book in 1930. It was an introduction to the theory of Fourier series (so named after Jean Baptiste Joseph Fourier ) and was written for students. The original was translated into English in 1959 and is still in use today. But after the National Socialists came to power , everything changed. In 1936 Wolfgang Rogosinski's venia legendi was revoked. He was only allowed to teach at a few Jewish schools in Berlin .

The Cambridge professors Godfrey Harold Hardy and John Edensor Littlewood , who had been in contact with Rogosinski for some time, invited him to come to England . Thanks to the generous support of the Society for the Protection of Science and Learning , he had lived with his wife and child in Cambridge since 1937, where he was involved in publications with Hardy and Littlewood. With GH Hardy he published five articles from 1943 to 1949 under the title Notes on Fourier series . A teaching position in Aberdeen in 1941 gave him his own modest income and the opportunity to continue working scientifically and to publish the results. 1945 Rogosinski went to Newcastle as a lecturer . In 1947 he was appointed Professor and in 1948 Head of Department . Here he was able to develop his excellent skills in the field of administration. His reputation as a good host was also well known. So he invited his doctoral students to a delicious meal after every colloquium . Many of his students later became professors or lecturers themselves. The cordial interaction with his students and colleagues meant that Rogosinski was only called “Rogo” by mathematicians around the world

In 1952 his book Volume and Integral was published . During the years in Newcastle, “Rogo” made contact with mathematicians there on various trips to the USA . 1959 Rogosinski resigned from his office in Newcastle. Svend Bundgaard brought him to the Mathematical Institute of Aarhus, which he directed . “Rogo” spent the last five years of his life here. In Denmark it became more popular than anywhere else. Auditors from all over the world came to Aarhus for his lectures. After Rogosinski had become a member of the Royal Society ( Fellow of the Royal Society ) in England in 1954 , he became a foreign member of the Royal Danish Academy of Sciences in 1962 . He made further trips across America and Mexico . He could no longer realize his intention to go from Aarhus to Brighton to the new University of Sussex .

In addition to his book publications, Rogosinski's bibliography shows 50 scientific articles. He died after a long illness at the age of 69 in Aarhus.
