Hans Jörg Stetter

from Wikipedia, the free encyclopedia

Hans Jörg Stetter (born April 8, 1930 in Munich ) is a German mathematician who deals with numerical analysis.

Hans Jörg Stetter, Halle 1974

Stetter studied at the University of Munich and then at the Technical University of Munich and was an exchange student at the Colorado State University at Fort Collins (then Agricultural College of Colorado), where he took part in the Putnam competition and received an honorable mention. Under Robert Sauer he turned to the numerics of partial (hyperbolic) differential equations (with applications in hydrodynamics and gas dynamics) at the Technical University of Munich and also received his doctorate in 1956 with a dissertation on numerical gas dynamics with Sauer (contributions to the interaction problem in linearized supersonic flow). From 1965 he was professor at the Technical University of Vienna (from 1975 Technical University).

Later he turned to the numerics of ordinary differential equations (ODE), for which he was considered a specialist (error analysis, asymptotic developments and others). Based on the ideas of the astronomer Pedro Elias Zadunaisky (and previously by Lewis Fry Richardson ), he developed an iterative method for error estimation in ODE (Defect correction method) in the 1970s. He also dealt with polynomial algebra on the borderline between numerical analysis and computer algebra.

In 1974 he was invited speaker at the International Congress of Mathematicians in Vancouver (Recent Progress on the numerical treatment of ordinary differential equations). In 1984 he became a member of the Leopoldina .
