from Wikipedia, the free encyclopedia

Johann Wiards Albert Schröder (born April 4, 1925 in Norden (East Frisia) , † January 3, 2007 ) was a German mathematician.

He studied mathematics and physics at the TH Hannover and the University of Göttingen . In 1952 he received his doctorate with his dissertation at the TH Hannover under Lothar Collatz on the subject of error estimates for perturbation calculations in linear eigenvalue problems .

In 1955 he was able to complete his habilitation. He has been teaching at the TH Braunschweig since 1955. He moved to the University of Hamburg in 1957, where he taught as an adjunct professor from 1961.

From 1963 he was appointed full professor at the University of Cologne . He was a visiting professor at Madison University from 1960 to 1961 and at Seattle University from 1964 to 1965 and 1969 to 1970, respectively. In 1986 he retired.

In 1966 he gave a plenary lecture at the International Congress of Mathematicians in Moscow (inequalities and error estimates).

He died in an accident and was buried in the Bensberg cemetery.
