Person: Bremermann, HansJoachim
HansJoachim Bremermann was a Germanborn American mathematician and biophysicist who worked on computer science and the mathematical theory of evolution.
Mathematical Profile (Excerpt):
 It was only when life began to return to some sort of normality after the war that HansJoachim was able to show his real abilities.
 Bremermann's doctoral studies were undertaken at the University of Münster.
 Naturally Bremermann too learned complex analysis and went on to make significant contributions to the field ...
 In 1951 Bremermann completed his Staatsexamen in mathematics and physics.
 In the year following the award of his doctorate Bremermann remained at Münster and taught there as an assistant.
 The year 1957 saw Bremermann move into a new area of research when he collaborated with the physicists R Oehme and J G Taylor applying his expertise in complex analysis to work on quantum field theory.
 In 1959 Bremermann accepted an appointment as associate professor of mathematics at the University of California, Berkeley.
 Let us now look briefly at Bremermann's research.
 Bremermann's thesis proved a special case of this result and subsequently he proved that the result is true in a further special case.
 In 1954 in Über die Aquivalenz der pseudokonvexen Gebiete und der Holomorphiegebiete im Raum von n komplexen Veränderlichen Ⓣ(On the equivalence of pseudoconvex regions and domains of holomorphy in the space of n complex variables) Bremermann proved the general theorem obtaining Oka's result for nnn complex variables where n≥2n ≥ 2n≥2.
 In 1961, in collaboration with L Durand, Bremermann produced a concrete approach to the representation of distributions by boundary values of analytic functions.
 In 1965 Bremermann published a book Distributions, complex variables, and Fourier transforms which gave an introduction to the theory of Schwartz distributions using the approach he had developed in his earlier work.
 Although he lived in the United States from 1952, it was not until 1965 that Bremermann became a naturalised American citizen.
 By the 1960s Bremermann's interests had turned towards the theory of computation and evolutionary biology.
Born 14 September 1926, Bremen, Germany. Died 21 February 1996, Berkeley, California, USA.
