The Number Theory Group at "Universität für Bodenkultur" in Vienna

(“BOKU – University of Natural Resources and Applied Life Sciences, Vienna”)

 

Historical remarks: At "Universität für Bodenkultur" in Vienna, analytic number theory has a remarkable tradition. In fact, since the early 1960's the mathematics chair was held by Karl Prachar whose contributions to the theory of primes (in particular his monograph Primzahlverteilung) obtained the highest esteem by mathematicians all over the world. After his retirement in 1992, a fortunate decision of the hiring committee made possible a successful continuation of this number theoretic tradition.


Nowadays, there is a small but efficient group working on topics like the theory of lattice points in large regions, the asymptotic behaviour of arithmetic functions, estimations of exponential sums, uniform distribution of sequences, Diophantine approximation, etc.: 

  • Werner Georg Nowak, at present head of the Institute of Mathematics, received his Ph.D. (1979) and his "Habilitation" (1983) from the University of Vienna, for work on generalizations on the Gauss circle problem, carried out under the supervision of Edmund Hlawka. His research concentrates on the theory of lattice points in large regions and on the asymptotic theory of arithmetic functions.
