Aryeh Dvoretzky
Aryeh Dvoretzky ( Hebrew אריה דבורצקי, Russian Арье Дворецкий ; * May 3, 1916 in Khorol ( Ukraine ); † May 8, 2008 in Jerusalem ) was an Israeli mathematician .
Life
The Dvoretzky family moved to Palestine in 1922 . He received his university degree in mathematics in 1937 from the then still young Hebrew University of Jerusalem . There he received his doctorate under Michael Fekete in 1941 and was appointed professor in 1951. He was Dean of the Faculty of Science (1955–1956), Vice President of the Hebrew University of Jerusalem (1959–1961), President of the Israel Academy of Sciences (1974–1980) and President of the Weizmann Institute of Sciences (1986–1989).
Dvoretzky's main areas of work were analysis and convexity theory , but he also wrote papers on probability theory . The Dvoretzky-Rogers theorem , published in 1950, is one of the starting points of modern Banach space theory . Dvoretzky's theorem , published 10 years later, about the finite presentability of in every infinite-dimensional Banach space is also of great importance .
In 1973 he was awarded the Israel Prize . In 1970 he was invited speaker at the International Congress of Mathematicians in Nice ( Central limit theorems for dependent random variables ). In 1985 the American Academy of Arts and Sciences made him a member. His students include Branko Grünbaum and Joram Lindenstrauss .
