German mathematician
Detlef Horst Müller (born 13 June 1954 in Dissen, Lower Saxony) is a German mathematician, specializing in analysis.
Müller received 1981 his doctorate from the University of Bielefeld with thesis "Das Syntheseverhalten glatter Hyperflächen mit homogenen Krümmungsverhältnissen im formula_1" (The synthesis behavior of smooth hypersurfaces with homogeneous curvature ratios in formula_1) under the supervision of Horst Leptin (1927–2017). Müller habilitated in 1984 in Kiel. He spent the academic year 1990–1991 at the Institute for Advanced Study. He was from 1992 to 1994 a professor at the Université Louis Pasteur in Strasbourg and is since 1994 a professor at the University of Kiel.
His research deals with harmonic analysis (especially related to Lie groups) with applications to partial differential equations.
In 1998 Müller was an Invited Speaker at the International Congress of Mathematicians in Berlin. He became a Fellow of the American Mathematical Society in the class of 2018. He is a member of the editorial boards of the "Journal of Lie Theory" and the "Annali di Matematica Pura ed Applicata".
