Otto Szász
Otto Szász , Hungarian Szász Ottó (born December 11, 1884 in Alsószúcs in Hungary , † December 19, 1952 in Cincinnati ) was a Hungarian mathematician who dealt with analysis .
Szász studied in Budapest and from 1907 to 1908 in Göttingen , and received his doctorate in 1911 at the University of Budapest under Leopold Fejér . In Göttingen he visited a. a. Lectures by David Hilbert , Felix Klein , Hermann Minkowski , Otto Toeplitz , Gustav Herglotz , Woldemar Voigt , Ludwig Prandtl . In 1911 he became a private lecturer in Budapest and attended the universities of Munich , Paris and Göttingen from 1911 to 1914 . In 1914 he became a private lecturer at the University of Frankfurt am Main and in 1920 a professor. Ousted from the university by the National Socialists in 1933, he emigrated to the USA, where he found a job at MIT and Brown University through Norbert Wiener . From 1936 he was a professor at the University of Cincinnati , where he stayed for the rest of his career, apart from a one-year research stay at the Institute for Numerical Mathematics at the University of Los Angeles .
Szász solved some problems that Oskar Perron posed in his textbook on continued fractions , gave a simpler (than before by Chaim Müntz ) proof of a problem by Sergei Bernstein in approximation theory (approximation of continuous functions on the unit interval by power functions whose powers form a positive sequence with diverging reciprocal sums ) and from a problem by Edmund Landau about the maximum amount of the partial sums of power series. Another area of work were Fourier series (including Taubers theorems, Gibbs phenomenon).
In 1939 he received the Julius König Prize of the Hungarian Academy of Sciences.
Kurt Mahler (1927) is one of his doctoral students .
