What university are both Hans Grauert and Hermann Weyl associated with?
Hans Grauert Hans Grauert (8 February 1930 in Haren, Emsland, Germany – 4 September 2011) was a German mathematician. He is known for major works on several complex variables, complex manifolds and the application of sheaf theory in this area, which influenced later work in algebraic geometry. Together with Reinhold Remmert he established and developed the theory of complex-analytic spaces. He became Professor at the University of Göttingen in 1958, as successor to C. L. Siegel. The lineage of this chair traces back through an eminent line of mathematicians: Weyl, Hilbert, Riemann, and ultimately to Gauss. Until his death, he was professor emeritus at Göttingen.
University of Düsseldorf Heinrich Heine University Düsseldorf (HHU) (German: "Heinrich-Heine-Universität Düsseldorf" ) was founded in 1965 as the successor organisation to Düsseldorf’s Medical Academy of 1907. Following several expansions throughout the decades, the university has comprised five faculties since 1993. At present, more than 20,000 full-time students are pursuing studies at HHU. There is a total staff of approximately 2,900 persons at HHU (academic and non-academic).
