Kurt Strebel (20 April 1921 – 26 October 2013) was a Swiss mathematician, specializing in geometric function theory.
received in 1953 his PhD from the University of Zurich under Rolf Nevanlinna with thesis Über das Kreisnormierungsproblem der konformen Abbildung (On the circle normalization problem of conformal mapping).
[2] The Nevanlinna Colloquium is usually held in Europe and covers most of classical complex analysis.
[3] In 1977 Strebel was elected a member of the Finnish Academy of Sciences.
Named in his honor is the Strebel differential in the Teichmüller theory.
