Background

His thesis in 1904 was devoted to the solution of Hilbert`s 19th problem. They found the conditions of analyticity of solutions of second-order equations of elliptic and parabolic type; developed new methods for solving boundary value problems for nonlinear elliptic equations; Together with his students created a new branch teoriifunktsy - constructive theory of functions. In the proof of the Weierstrass approximation theorem Bernstein polynomials were constructed, proved useful in many different areas of mathematics. Now they are called Bernstein polynomials.

In the theory of probability Bernstein offered the first (1917) axiomatic; continued and completed in a certain sense, the study of the St. Petersburg school of Chebyshev - Markov on limit theorems; developed a theory of weakly dependent random variables; We studied stochastic differential equations and identifies a number of applications of probabilistic methods in physics, statistics and biology.
