Journée Georges de Rham

deRhambande.jpg

The Journée Georges de Rham was introduced in 1991 by the Troisième cycle Romand de mathématiques. Since then, it has been organized each year during the Spring semester by the mathematics departments of EPFL and of the University of Geneva. The organisers invite two internationally renowned speakers. The aim is to present current developments in mathematics, as well as stimulating interactions amongst researchers in mathematics and related fields.
