BOGOLYUBOV 56 



Physics of the Joint Institute of Nuclear Research in Dubno. 

 He established the School of Nonlinear Mechanics in Kiev and 

 the School of Theoretical Physics in Moscow. These schools 

 have made a great contribution both to the development of theo- 

 retical science and to the solution of numerous practical prob- 

 lems of modern physics and engineering. Bogolyubov has been 

 invited many times to deliver lectures on his research at 

 foreign universities and scientific research institutes, as well 

 as at international congresses and conferences. A number of 

 his monographs have been translated into foreign languages. 



In 1939, Bogolyubov was elected Corresponding Member of 

 the Academy of Sciences of the Ukrainian S.S.R., in 1947 Corre- 

 sponding Member of the Academy of Sciences U.S.S.R., and in 

 1948 an Academician of the Academy of Sciences of the Ukraini- 

 an S.S.R. In 1953, he was elected Academician by the Academy 

 of Sciences U. S.S.R. He received an honorary doctorate from 

 the University of Hyderabad. For his research in the field of 

 nonlinear mechanics and statistical physics, set forth in the 

 monographs, "On Some Statistical Methods in Mathematical 

 Physics," and "Problems of Dynamic Theory in Statistical 

 Physics," Bogolyubov received in 1947 a Stalin Prize, First 

 Class. For his investigation in superconductivity, he was 

 awarded the Lomonosov Prize in 1957. In 1958, he was award- 

 ed the Lenin Prize for working out the new methods in quantum 

 field theory and in statistical physics which had led, in particu- 

 lar, to substantiation of the theory of superfluidity and the 

 theory of superconductivity. Other awards he has received in- 

 clude another Stalin Prize and seven orders, among them three 

 Orders of Lenin and the Order of the Red Banner of Labor. 



The scientific activity of Bogolyubov, which has extended 

 over more than 30 years, covers varied fields of analysis, 

 function theory, differential equations, theory of vibrations, 

 theory of stability, and quantum field theory. During the period 

 of his productive scientific inquiry, he published over 170 scien- 

 tific papers, including a series of fundamental monographs. 

 The following is a brief outline of the principal lines of his 

 work. 



His earliest research was in the field of the calculus of vari- 

 ations. This research was devoted to the development of direct 

 methods for the solution of extreme problems which do not re- 

 quire regularity or quasi -regularity of the corresponding oper- 

 ations. At an international congress devoted to problems of the 

 calculus of variations, his paper entitled "New Methods in the 

 Calculus of Variations," was awarded the A. Mertani Prize of
