Yevgeny Mikhailovich Nikishin
Yevgeny Mikhailovich Niki Schin , Russian Евгений Михайлович Никишин , English transcription Evgenii Mikhailovich Nikishin, (* 23. June 1945 in Penza , † 17th December 1986 ) was a Russian mathematician who with Harmonic Analysis dealt.
life and work
Nikischin studied at Lomonosov University with a doctorate in 1969 and did research at the Steklow Institute , where he completed his habilitation in 1971 (Russian doctorate with Pyotr Lavrentjewitsch Ulyanov , 1928-2006). From 1977 he was a professor at Lomonossow University. He died after a long and serious illness.
He dealt with approximation using function systems, for example Padé approximation . Nikishin systems of functions and the theorem of Nikishin and Stein are named after him, a generalization of Stein's factorization theorem that he found in 1970 . He also considers rational approximation in number theory and treats it together with rational approximations in function spaces in a monograph.
In 1973 he received the Salem Prize . In 1972 he received the Lenin Komsomol Prize. In 1978 he was invited speaker at the International Congress of Mathematicians in Helsinki (The Padé Approximants).
