Wolfgang Soergel (born 12 June 1962 in Geneva) is a German mathematician, specializing in geometry and representation theory.

Biography

He spent his youth in Heidelberg, where he passed the Abitur examination in 1980 at the Kurfürst-Friedrich-Gymnasium Heidelberg [de]. He studied mathematics and physics in Geneva and Bonn and received his Promotion (PhD) in 1988 from the University of Hamburg. His PhD dissertation Universelle versus relative Einhüllende: Eine geometrische Untersuchung von Quotienten von universellen Einhüllenden halbeinfacher Lie-Algebren (Universal versus relative envelopes: a geometric investigation of quotients of universal envelopes of semi-simple Lie algebras) was supervised by Jens Carsten Jantzen.^[1] After postdoctoral positions at U. C. Berkeley, Harvard University, and MIT, Soergel completed his Habilitation at the University of Bonn in 1991. In 1994 he was appointed to a professorial chair at the University of Freiburg. He was an invited speaker at the 1994 International Congress of Mathematicians in Zurich. Since 2008 he has been a full member of the Heidelberg Academy of Sciences and Humanities.^[2]

He is the author or coauthor of over 30 research articles.^[3] His research in representation theory has important applications to Kazhdan-Lusztig theory and Koszul duality. The category of Soergel bimodules is named in his honor.^[4][5]

His doctoral students include Peter Fiebig, Catharina Stroppel and Geordie Williamson.^[1]

Wolfgang Soergel is the son of the physicist Volker Soergel [de] and a grandson of the paleontologist Johannes Wolfgang Adolf Werner Soergel [de] (1887–1946).
