From Wikipedia, the free encyclopedia

Heini Halberstam is a British mathematician, working in the field of analytic number theory. He is one of the two mathematicians after whom the Elliott-Halberstam conjecture is named. He obtained his Ph.D. in 1952, from University College, London, under supervision of Theodor Estermann. From 1964 until 1980, Halberstam was a Professor of Mathematics at Nottingham University; in 1980, he took up a position at the University of Illinois, Urbana Champaign (UIUC); he became an Emeritus Professor at UIUC in 1996.

He is well known also for books, with Klaus Roth on combinatorial number theory, and with H. E. Richert on sieve theory.
