Boris Jakowlewitsch Levin
Boris Jakowlewitsch Lewin , Russian Борис Яковлевич Левин , English transcription Boris Yakovlevich Levin, (born December 22, 1906 in Odessa , † August 24, 1993 in Kharkiv ) was a Ukrainian mathematician who dealt with analysis .
His father was an employee of a Black Sea shipping company and Lewin grew up in many places on the Black Sea. He finished school in Yeisk and then worked in various professions, including a welder in pipeline construction, before he was able to study at Rostov University from 1928. His mathematics professor and analyst was Dmitri Dmitrijewitsch Morduchai-Boltowskoj (1876-1952) and a fellow student Nikolai Vladimirovich Efimov . He graduated in 1932 and then taught at the Rostov Polytechnic. When higher degrees were again introduced at the universities of the Soviet Union in 1934, he submitted a dissertation at the Rostov University in 1936 (for the candidate title, corresponding to a doctorate), but was immediately qualified as a professor (Russian doctorate). The topic of the dissertation was: About the growth of an entire function along a ray and the distribution of its zeros . During this time he taught at the University of Marine Engineers in Odessa. At the same time he worked with Mark Grigoryevich Kerin , who was a professor at the university there and with whom he became friends. Another friend was Naum Ilyich Achijeser .
During the Second World War, like the rest of the university, he was evacuated to Samarkand and after the war the functional analysis group around Kerin disbanded because he had been forced out of the university (he was accused of having too many Jewish students).
In 1949 he went to the University of Kharkiv as a professor at the invitation of Naum Achiejeser . From 1969 he was also head of the functional theory department at the Institute for Low Temperature Physics of the Ukrainian Academy of Sciences in Kharkiv. Despite his reputation, he had a difficult position at the university and obstacles were placed in his way (for example he was excluded from doctoral examinations), so that at times he only came to the function theory seminar, which he led with Ostrowski.
He dealt with complex analysis and functional analysis, for example the theory of whole functions, about whose zero distribution he wrote a research monograph, and almost periodic functions.
With Anatoli Asirowitsch Goldberg and Jossif Wladimirowitsch Ostrowski he received the State Prize of the Ukraine in 1992. One of his PhD students included Ostrowski and Vitali Milman .
