Elias Wegert

from Wikipedia, the free encyclopedia

Elias Wegert (born March 20, 1955 in Nossen ) is a German mathematician whose main research interests are nonlinear analysis and function theory . In particular, he works on non-linear Riemann-Hilbert problems and the visualization of complex functions .

Career

Wegert passed the Abitur in 1973 in the special class for mathematics at the Technical University of Karl-Marx-Stadt (Chemnitz). As a participant in the International Mathematical Olympiad , he received a silver medal in 1973. From 1975 to 1980 Wegert studied mathematics at the TH Karl-Marx-Stadt and received his doctorate in 1984 with Wolfgang Sprössig on a topic from constructive approximation theory. In 1988 he completed his habilitation at the TU Bergakademie Freiberg with a thesis on non-linear Riemann-Hilbert problems. Wegert has been Professor of Nonlinear Analysis at the TU Bergakademie Freiberg since 1992.

Wegert has been involved in developing tasks for the Mathematics Olympiad for some time . The Pentagon problem he posed at the International Mathematical Olympiad in 1986 was only solved by eleven participants, making it one of the IMO's most difficult tasks to date.
