Hellmut Baumgärtel

from Wikipedia, the free encyclopedia

Hellmut Baumgärtel (* 1934 in Oelsnitz , Vogtland ) is a German mathematician and university professor .

Life

Baumgärtel graduated from high school in Zittau in 1952 with a high school diploma. There he received mathematics lessons from Rudolf Hunger, whose teaching activities resulted in three mathematics professors: Manfred Peschel , Hellmut Baumgärtel and Albrecht Pietsch . ( Werner Müller was also a later student at this grammar school.)

He received his doctorate in 1964 with a thesis on the theory of the paraboloid differential equation and Whittaker's functions under Kurt Schröder at the Humboldt University in Berlin . In 1968 he completed his habilitation with a thesis on contributions to the mathematical theory of general and special scattering systems at the Humboldt University. He was at the Karl Weierstrass Institute of the Academy of Sciences of the GDR and professor at the Academy of Sciences. After reunification he was a professor at the University of Potsdam .

In 1968 and 1971 he gave lectures at the Institute for Mathematics of the Moldavian SSR in Kishinev with Israel Gohberg . From 1992 to 1997 he worked on the project SFB 288: Differential Geometry and Quantum Physics as head of the sub-project Inclusions of Algebras and Quantum Field Theory (F 2E) .

Baumgärtel's research focuses on functional analysis and mathematical physics, for example perturbation theory of operators and algebraic quantum field theory .
