His first results concern quadratic forms\, and norms of number fields. Ov er 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 L ee.\n DTSTART:20180413T200000Z DTEND:20180413T210000Z LOCATION:Room PK-5115 \, CA\, Pavillon President-Kennedy\, 201 Ave. Preside nt-Kennedy SUMMARY:Eva Bayer\, École Polytechnique Fédérale de Lausane URL:/mathstat/channels/event/eva-bayer-ecole-polytechn ique-federale-de-lausane-286404 END:VEVENT END:VCALENDAR
