Galois actions on operads

Hot Topics: Galois Theory of Periods and Applications March 27, 2017 - March 31, 2017

March 28, 2017 (03:30 PM PDT - 04:30 PM PDT)
Speaker(s): Geoffroy Horel (Université de Paris XIII (Paris-Nord))
Location: MSRI: Simons Auditorium


The Grothendieck-Teichmüller group is a profinite group that contains the absolute Galois group of the rational numbers and is conjecturally isomorphic to it. In this talk I will explain how one can understand this group using the homotopy theory of operads. This is joint work with Pedro Boavida de Brito and Marcy Robertson
