Konrad Jörgens

Konrad Jörgens (1971)

Konrad Jörgens (born December 3, 1926 in Krefeld ; † April 28, 1974 ) was a German mathematician . He made important contributions in the context of mathematical physics , in particular for the fundamentals of quantum mechanics and for the theory of partial differential equations and integral operators.

Life

He studied at the TH Karlsruhe (1949/51) and the University of Göttingen (1951/54), where he received his doctorate in 1954 under Franz Rellich on the subject of harmonic maps and the differential equation ${\displaystyle rt-s^{2}=1}$ . He then worked at the Max Planck Institute for Physics and Astrophysics in Göttingen from 1954 to 1958 with an interim (1956/57) guest stay at New York University and from 1958 assistant at the Institute for Applied Mathematics in Heidelberg, where he met in July 1959 habilitation. In June 1961 he was appointed to the newly created associate professor for applied and practical mathematics at the same institute. In 1966 he became a regular full professor for applied mathematics in Heidelberg.

One of Jörgens' assumptions is still open today: Be up . and M is a finite union of closed submanifolds of . Furthermore, let it be essentially self-adjoint to (where the set of smooth functions with compact support is) and restricted from below. Then it is essentially self-adjoint . ${\displaystyle W(x)\geq V(x)}$ ${\displaystyle \mathbb {R} ^{\nu }}$ ${\displaystyle \mathbb {R} ^{\nu }}$ ${\displaystyle -\Delta +V}$ ${\displaystyle C_{0}^{\infty }(\mathbb {R} ^{\nu }\setminus M)}$ ${\displaystyle C_{0}^{\infty }}$ ${\displaystyle -\Delta +W}$ ${\displaystyle C_{0}^{\infty }(\mathbb {R} ^{\nu }\setminus M)}$
