Ruth Kellerhals

from Wikipedia, the free encyclopedia

Ruth Kellerhals (born July 17, 1957 ) is a Swiss mathematician who deals with hyperbolic geometry .

Kellerhals attended grammar school in Basel and studied at the University of Basel with a diploma in 1982 with Heinz Huber (on the finiteness of the isometric group of a compact Riemann manifold of negative curvature) and his doctorate in 1988 (on the content of hyperbolic polyhedra in dimensions three and four) with Hans -Christoph Im Hof . In 1983/84 she also studied at the University of Grenoble (Institut Fourier). In 1995 she completed her habilitation at the University of Bonn , where she was at the Max Planck Institute for Mathematics from 1989 to 1995 . There she was also the assistant to Friedrich Hirzebruch . From 1995 she was assistant professor at the University of Göttingen , from 1999 titular professor at the University of Bordeaux I and from 2000 professor at the University of Friborg , where she was visiting professor in 1998/99.

She deals with hyperbolic geometry, geometric group theory and geometry of discrete groups, discrete and convex geometry, volumes of manifolds and polylogarithms.

She also dealt with the work of Ludwig Schläfli .

She has been visiting scholar at MSRI , IHES , the Mittag-Leffler Institute , the State University of New York at Stony Brook , the RIMS in Kyoto, the City University Osaka, the ETH Zurich , the University of Bern and the University of Auckland in Helsinki , Berlin and Budapest.

She is a citizen of Hägendorf .
