Sobolev introduced notions which are now fundamental in several different areas of mathematics. Sobolev spaces can be defined by growth conditions on Fourier transforms; they and their embedding theorems are an important subject in functional analysis. Generalized functions (later known as distributions), were first introduced by Sobolev in 1935 and further developed by Laurent Schwartz; they redefined the notion of differentiation. Both these developments grew directly out of his work on partial differential equations. In mathematics, a Sobolev space is a normed space of functions obtained by imposing on a function f and its derivatives up to some order k the condition of finite Lp norm, for given p ≥ 1. ...

Sobolev graduated from the Leningrad University in 1929. He worked at the Steklov Institute of Mathematics in Leningrad from 1932, and in Moscow from 1934. He headed the institute when it was evacuated to Kazan during the World War II. He was a Moscow State University professor from 1935 to 1957 and also a deputy director of the Institute for Atomic Energy 1943-57.
