Biography
Born in Freiburg .
In 1946 he entered the University of Freiburg , where he studied mathematics and physics. In 1950 he defended his thesis on the topic “Cohomological theory of topological spaces” ( German Eine Cohomologietheorie topologischer Räume ) and received his doctoral degree ( Dr. rer. Nat. ). His supervisors were: first , and then Wilhelm Süss [1] .
In 1952-1957 he worked at , which at that time was located in Göttingen . There he joined the Werner Heisenberg group, in which he conducted joint research with and [2] .
Two academic years (1957–1958 and 1960–1961), he worked at the Institute for Advanced Study in Princeton ( New Jersey , USA ) [4] . In 1962 he received the position of professor at New York University . There he continued his scientific work and, in particular, developed the theory of renormalization in quantum field theory [2] .
In 1973 [5] (according to other sources, in 1974 [6] ) he moved to the Max Planck Institute for Physics and Astrophysics, which was located in Munich . After the separation of the institute in 1991, he continued work at , where he was a member of the board of directors, as well as the director of the institute. Until 1996, when he became an Emeritus Professor , the scientist led the Department of Quantum Field Theory and Elementary Particle Physics, which was part of the institute [5] .
Scientific Results
Working together with and , he created an axiomatic description of quantum field theory, which later became known as Lehmann-Symanzik-Zimmermann formalism ( LSZ formalism ). Although this approach was originally formulated outside the framework of perturbation theory , it later proved to be very useful in describing the scattering amplitudes of elementary particles in the framework of perturbation theory [2] .
Working on the renormalization theory , he presented an explicit solution to the recursive procedure for obtaining final results for Feynman diagrams proposed by Nikolai Bogolyubov , Ostap Parasyuk and . Subsequently, this procedure, originally based on the Bogolyubov – Parasyuk theorem , was called the Bogolyubov – Parasyuk – Hepp – Zimmermann renormalization scheme (BPHC, English BPHZ renormalization scheme ) [2] .
Awards and prizes
- The Max Planck Medal (1991) [7] - "for his contribution to quantum field theory and renormalization theory" [3] .
