Ezhov , mathematical methods of statistical mechanics D. During this period, scientists of the Institute had been carrying out research on such important areas of mathematics as algebra, topology, theory of functions, functional analysis, theory of ordinary differential equations and partial differential equations, mathematical physics and theory of nonlinear oscillations, probability theory and mathematical statistics, mathematical methods of mechanics, computational mathematics, mathematical modeling and applied mathematics.

In theory of nonlinear oscillations asymptotic methods were developed for higher order equations and partial derivatives, adiabatic invariants were constructed for broad classes of dynamical systems, and important theorems of the theory of stability were proved Yu.
