Willi Jäger
Willi Jäger is a German mathematician.
Education
He completed his PhD in 1966 the University of Munich under the direction of Erhard Heinz.Career
From 1969 to 1970 Jäger was a visiting scientist at the Courant Institute in New York City. In 1970 he became professor of mathematics at the University of Münster and from 1974 he became professor of applied mathematics at the Heidelberg University. In 1987 Jäger was founding member of the Interdisciplinary Center for Scientific Computing in Heidelberg. He is a board member of the Mathematical Research Institute of Oberwolfach.In addition to problems of scientific computing, including the effective use of computers for the mathematical modeling of complicated, mostly scientific problems, Jäger deals with problems of nonlinear differential equations, calculus of variations, branching processes, and the spectral theory of differential operators, mostly with a view to specific applications such as data visualization.
Jäger had more than 100 PhD students, including Florin Diacu, Bernold Fiedler, Stephan Luckhaus, Hubert Mara and Martin Vingron.
