Hans-Egon Richert
Hans-Egon Richert (born June 2, 1924 in Hamburg ; † November 25, 1993 in Blaustein ) was a German mathematician who deals with analytical number theory.
Richert went to school in Hamburg (due to "anglophile inclinations" he was expelled from the public school and he had to attend a private school) and studied mathematics at the University of Hamburg from 1946 after his military service in World War II . In 1950 he received his doctorate there under Max Deuring and completed his habilitation in 1954. He was then at the University of Göttingen and then professor at the University of Marburg . In 1972 he moved to the newly founded University of Ulm , where he retired in 1991. 1974/75 he was Vice Rector of the University. He was visiting professor at the Tata Institute of Fundamental Research and at the University of Illinois at Urbana-Champaign (near Halberstam). He was also a co-organizer of the Oberwolfach meeting in analytical number theory. From the 1960s on, Richert dealt in particular with sieving methods, about which he wrote a standard work with Heini Halberstam . It also contains a simplification of Jingrun Chen's sentence from the context of the Goldbach conjecture . He also made progress with the asymptotic formula for Dirichlet's number function (in 1953 he achieved an upper limit of 15/46 for the infimum of the exponent of the residual term in the asymptotic formula).
