Bogoliubov, Nikolai

Bogoliubov, Nikolai [Боголюбов, Николай; Bogoljubov, Nikolaj], b 21 August 1909 in Nizhnii Novgorod, Russia, d 13 February 1992 in Moscow. Mathematician, theoretical physicist, and specialist in mechanics; from1948 a full member of the Academy of Sciences of the Ukrainian SSR and from 1953 a full member of the Academy of Sciences of the USSR. In 1936–50 Bogoliubov taught at Kyiv University and served as head of the department of mathematical physics at the Institute of Mathematics of the Academy of Sciences of the Ukrainian SSR. In 1950 he moved to Moscow, and in 1965 he was appointed director of the Joint Institute for Nuclear Research in Dubno. With Mykola Krylov Bogoliubov founded non-linear mechanics. His basic works deal with the theory of dynamic systems, approximation methods of mathematical analysis, mathematical physics, statistical physics, and quantum field theory. Bogoliubov worked out the mathematical foundations of a consistent microscopic theory of superfluidity (1947) and constructed a mathematical theory of super-conductivity (1958). He established a school of non-linear mechanics in Kyiv and a school of theoretical physics in Moscow. The Institute of Theoretical Physics of the National Academy of Sciences of Ukraine has been dedicated to the memory of Bogoliubov and now bears his name.
