In 1966 he got his PhD at the University of Erlangen under the supervision of Heinz Bauer. His main research area at that time was abstract potential theory, with 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. After an appointment to Bielefeld, he became professor of mathematics at the University of Bremen.
Hinrichsen was the founding director of the Research Center for Dynamical Systems, concentrating on finite- and infinite-dimensional linear systems, stochastic dynamical systems, nonlinear dynamics and stability analysis.
He focused on algebraic systems theory, parameterization problems in control and linear algebra, infinite-dimensional systems, and stability analysis, developing a comprehensive theory of linear systems. 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.
