Diederich Hinrichsen (born 17 February 1939) is a German mathematician who, together with Hans W. Knobloch, established the field of dynamical systems theory and control theory in Germany.
Diederich Hinrichsen was born in 1939, and studied mathematics, physics, literature, philosophy, and economics from 1958 to 1965 in Hamburg.
[1] His main research area at that time was abstract potential theory, with a special focus on extensions of the Cauchy-Weil theorem to the Choquet boundary.
After research visits in Paris and Hamburg, he went to Havana where he helped to re-establish mathematics in Cuba.
In a different direction, with Anthony J. Pritchard (University of Warwick), he worked on concepts of stability radii and spectral value sets, building up a robustness theory covering deterministic and stochastic aspects of dynamical systems.
