6 October 1908 -3 January 1989 ) was aRussia nmathematician , working inmathematical analysis andpartial differential equation s. He was born in St. Petersburg, and died inMoscow .Sobolev introduced the notions that are now fundamental for several different areas of mathematics.
Sobolev space s can be defined by some growth conditions on theFourier transform s; they and their embedding theorems are an important subject infunctional analysis .Generalized function s (later known as distributions), were first introduced by Sobolev in 1935 forweak solution s, and further developed byLaurent Schwartz . Sobolev abstracted the classical notion of differentiation so expanding the ranges of applications of the technique of Newton and Leibniz. The theory of distributions is considered now as the calculus of the modern epoch.Sobolev graduated from Leningrad University in 1929, where he was a student ofNikolai Maksimovich Günter. After graduation he worked with Vladimir Smirnov whom he considered as his second teacher. He worked in Leningrad from 1932, and at the
Steklov Institute of Mathematics in Moscow from 1934. He headed the institute inevacuation toKazan during theWorld War II . He was aMoscow State University professor from 1935 to 1957 and also a deputy director of the Institute for Atomic Energy 1943-57 where he participated in theA-bomb project of the USSR.In 1956 Sobolev joined a number of prominent scientists in proposing a large-scale scientific and educational initiative for the Eastern parts of the
Soviet Union , which resulted in the creation of the Siberian Division of the Academy of Sciences. He was the founder and first director of the Institute of Mathematics atAkademgorodok nearNovosibirsk , which was later to bear his name, and played an important role in the establishment and development ofNovosibirsk State University .ee also
