Jurg Fruhlich
JĂźrg Martin FrĂśhlich is a Swiss mathematician and theoretical physicist. Born 4 July 1946 in Schaffhausen. In 1965 FrĂśhlich began to study mathematics and physics at EidgenĂśssischen Technischen Hochschule ZĂźrich. In 1969 he attained under Klaus Hepp and Robert Schrader the Diplom (âDressing Transformations in Quantum Field Theoryâ), and 1972 he earned a PhD from the same institution under Klaus Hepp. After postdoctoral visits to the University of Geneva and Harvard University (with Arthur Jaffe), he took an assistant professorship in 1974 in the mathematics department of Princeton University. From 1978 until 1982 he was a professor at Institut des Hautes Ătudes Scientifiques in Bures-sur-Yvette in Paris, and since 1982 he has been a professor for theoretical physics at ETH, where he founded the Center for Theoretical Studies.
In 1978, FrĂśhlich gave an invited address to the International Congress of Mathematicians in Helsinki (âOn the mathematics of phase transitionsâ) and in 1994 at the plenary talk of the ICM in Zurich (âThe FQHE, ChernâSimons Theory and Integral Latticesâ). He also co-authored a book on quantum triviality. FrĂśhlich works on quantum field theory (including axiomatic quantum field theory, conformal field theory, and topological quantum field theory), on the precise mathematical treatment of models of statistical mechanics, on theories of phase transition, on the fractional quantum Hall effect, and on non-commutative geometry.
