About Sergei Sobolev

  • Prof Sergei Lvovich Sobolev (Russian: ?????´? ????´??? ??´?????) HFRSE (6 October 1908 – 3 January 1989) was a Soviet mathematician working in mathematical analysis and partial differential equations. Sobolev introduced notions that are now fundamental for several areas of mathematics.
  • Sobolev spaces can be defined by some growth conditions on the Fourier transform.
  • 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 for weak solutions, and further developed by Laurent Schwartz.
  • Sobolev abstracted the classical notion of differentiation, so expanding the range of application of the technique of Newton and Leibniz.
  • The theory of distributions is considered now as the calculus of the modern epoch.
