Martín Safe visits the GREYC Lab at Caen

From February 23 to March 23, 2020, Martín Safe is visiting the GREYC Laboratory at Caen (France), and more particularly its AMACC team. He is invited on a “Chaire d’Excellence” inside the ALENOR Project, (a regional project between theuniversities of Caen, Rouen and Le Havre, Normandy).


The last week (16-22 March), he is invited at the CIRM (Centre international de Recherches Mathématiques, Marseille), for the Alea Journées of the GDR IM, and gives a talk on a joint work inside the SINFIN team (co-authored with Valérie Berthé, Eda Cesaratto, Frédéric Paccaut, Pablo Rotondo, Martin Safe, Brigitte Vallée)
