The importance of the Selberg integral

Forrester, Peter J., Warnaar, S. Ole

Understand

It has been remarked that a fair measure of the impact of Atle Selberg's work is the number of mathematical terms which bear his name.

  • One of these is the Selberg integral, an n-dimensional generalization of the Euler beta integral.
  • We trace its sudden rise to prominence, initiated by a question to Selberg from Enrico Bombieri, more than thirty years after publication.
  • In quick succession the Selberg integral was used to prove an outstanding conjecture in random matrix theory, and cases of the Macdonald conjectures.
