The Bogolyubovs relocated to the village of Velikaya Krucha in the (now in, ) in 1919, where the young Nikolay Bogolyubov began to study physics and mathematics. The family soon moved to in 1921, where they continued to live in poverty as the elder Nikolay Bogolyubov only found a position as a priest in 1923. He attended research seminars in and soon started to work under the supervision of the well-known contemporary mathematician. In 1924, at the age of 15, Nikolay Bogolyubov wrote his first published scientific paper On the behavior of solutions of linear differential equations at infinity. In 1925 he entered Ph.D. Program at the Academy of Sciences of the and obtained the degree of ( Candidate of Sciences, equivalent to a Ph.D.) in 1928, at the age of 19, with the doctoral thesis titled On direct methods of variational calculus.

In 1930, at the age of 21, he obtained the degree of ( Doctor of Sciences, equivalent to ), the highest degree in the Soviet Union, which requires the recipient to have made a significant independent contribution to his or her scientific field. This early period of Bogolyubov's work in science was concerned with such mathematical problems as direct methods of the, the theory of, methods of approximate solution of,. This earlier research had already earned him recognition. One of his essays was awarded the Prize in 1930, and the author was awarded the erudite degree of doctor of mathematics. This was the period when the scientific career of the young Nikolai Bogolyubov began, later producing new scientific trends in modern mathematics, physics, and mechanics. Since 1931, Krylov and Bogolyubov worked together on the problems of nonlinear mechanics and nonlinear oscillations. They were the key figures in the 'Kiev school of nonlinear oscillation research', where their cooperation resulted in the paper ' On the quasiperiodic solutions of the equations of nonlinear mechanics' (1934) and the book Introduction to Nonlinear Mechanics (1937; translated to English in 1947) leading to a creation of a large field of non-linear mechanics.

And this can explain, as the authors believe, the need to shape the collection of problems of non-linear perturbation theory into a special science, which could be named NON-LINEAR MECHANICS.

From a point of view, the key achievement of the Kiev School was the development by Krylov and Bogolyubov of the method for the analysis of nonlinear control problems. In the period 1928—1973, Nikolay Bogolyubov worked in the of the Academy of Sciences of the Ukrainian SSR holding the position of the Director of the institute since 1965. He lectured at Kiev University in the period 1936—1959. In evacuation (1941–1943) [ ] After the against the on 22 June 1941 (beginning of the ), most institutes and universities from west part of Russia were evacuated into east regions far from the battle lines. Nikolay Bogolyubov moved to, where he became Head of the Departments of Mathematical Analysis at and at, remaining on these positions during the period of July 1941 – August 1943. Moscow (1943–?) [ ] In autumn 1943, Bogolyubov came from evacuation to Moscow and on 1 November 1943 he accepted a position in the Department of Theoretical Physics at the (MSU). At that time the Head of the Department was (for a short period in 1944 the Head of the Department was ).
