Colloque par Eva Bayer-Fluckiger (École Polytechnique Fédérale de Lausanne)
One of the classical tools of number theory is the socalled localglobal principle, or Hasse principle, going back to Hasse's work in the 1920's. His first results concern quadratic forms, and norms of number fields. Over the years, many positive and negative results were proved, and there is now a huge number of results in this topic. This talk will present some old and new results, in particular in the continuation of Hasse's cyclic norm theorem. These have been obtained jointly with Parimala and Tingyu Lee.
