For the next two days we have the pleasure of hosting Prof. Marc Henneaux, a renown theoretical physicist from Collège de France. Marc is here as visiting chair within the University of Trento-College de France visiting chair program (similarly to Prof. Françoise Combes last year). He will be delivering two seminars by the title of “Ultrarelativistic Limits of Gravity and Carroll Group” and a colloquium by the title of “Asymptotic Symmetries in Gauge Theories with Emphasis on Gravity”. Welcome Marc!
