Aurel Wintner
Aurel Wintner Friedrich ( born April 8, 1903 in Budapest, † January 15, 1958 in Baltimore ) was an American mathematician of Hungarian origin, dealt primarily with Analysis and celestial mechanics.
Life and work
Wintner pointed to the school in Budapest both musical ( it played the violin very well, but gave the benefit of mathematics with 17 years fully on ) as well as mathematical talent. Was by his uncle Samuel Oppenheim (1857-1928), professor of astronomy in Vienna, he also became interested in astronomy. 1920 to 1924 he studied at the University of Budapest. A whole series of mathematical and astronomical publications in subsequent years gave him in 1927 an invitation from Leon Lichtenstein in Leipzig (himself worked on the application of the calculus of variations, for example, on the equilibrium figures of celestial bodies ), where he supported Lichtenstein in the publication of the Mathematische Zeitschrift in 1929 received his doctorate. There he proved in the effort, the works of George William Hill on the theory of the moon, in the Hill infinite matrices used to justify strict, many basic theorems from the theory of Hilbert spaces, while John von Neumann, who thereby the foundations of quantum mechanics had in mind in the same field has been very active and overshadowed the results Wintners in the sequence. 1929 to 1930 he attended on a scholarship Tullio Levi -Civita in Rome and astronomers Bengt Strömgren in Copenhagen. In 1930 he married the daughter of his teacher Otto Hölder Leipzig and was appointed professor at Johns Hopkins University in Baltimore, where in 1941 he received a full professorship.
His interest in astronomy ( and his efforts to celestial mechanics to put on solid mathematical foundations ) not only led to his involvement with Hilbert spaces, but also other problems of analysis as almost periodic functions, distribution functions, Fourier series, Taubersche rates as well as with analytic number theory, probability theory, ergodic theory, where it came Vienna to work with George David Birkhoff and Norbert.
In 1944 he became editor of the American Journal of Mathematics. He was married to the chemist Irmgard Hoelder since 1930 and had a son.
