Vladimir Steklov was born December 28, 1863 (January 9, 1864) in Nizhny Novgorod, died May 30, 1926 in the Crimea, is buried in Leningrad.

In 1919-26, Vice-President of the USSR. In 1887 he graduated from Kharkov University, where he studied under a. M. Lyapunov. In 1889-1906 he worked at the Department of Mechanics at Kharkov University, first as assistant, then a privat-docent (since 1891) and professor (since 1896).

In 1893-1905 was a professor of theoretical mechanics of Kharkov Institute of Technology. In 1894, he defended his master's thesis 'On the motion of a rigid body in a liquid' (ed. 1893), and in 1902 - a doctoral thesis 'The general methods for solving the basic problems of mathematical physics' (ed. 1901).

In 1906 the Steklov moved to the St. Petersburg University. Conducted a great social and scientific-organizational work, especially in the last years of life. On his initiative, organized with the Physical Sciences and Mathematics Institute (1921), whose director he was before the end of his life. In 1926 the name was given Steklov Mathematical Institute of Physics, who in 1934 split into two institutions (one of them - Mathematical Institute, USSR Academy of Sciences retained the name of the Steklov).

. The main directions of scientific creativity Steklov - the application of mathematical methods to questions of natural science, most of his work relates to mathematical physics
. Steklov received a number of significant results concerning the basic problems of potential theory. For functions, vanishing on the boundary, Steklov brought functional inequality of Poincare type inequality with an exact constant.

The majority of works devoted to the issues of expansion of the Steklov functions in series of preassigned orthogonal systems of functions, such systems usually result in boundary problems of mathematical physics. The basis of these studies is the notion of isolation imposed Steklov system of orthogonal functions.

Steklov came very close to the concept of a Hilbert space. In the study of issues of expansions in series Steklov developed asymptotic methods, among them - a method of obtaining asymptotic expressions for the classical orthogonal polynomials, called the method of Liouville - Steklov. Installed Steklov theorem on the decomposability of the generalized Fourier series is very close to t. n. theorems 'equiconvergence'. Steklov introduced a special method of smoothing functions, which then received a large development.

Glass - the author of several works on mathematical analysis, in particular the theory of quadrature formulas, as well as the theory of elasticity and fluid mechanics. Steklov Mathematics, known as a historian, philosopher and writer.
