Abstract
I will report on recent work concerning the action of the motivic Galois group on anabelian objects such as fundamental groups of algebraic varieties conveniently completed. I’ll sketch the proof of a motivic analog of a theorem of Pop (aka., the Ihara-Matsumoto-Oda conjecture) yielding an interpretation of the motivic Galois group as the automorphism group of a large diagram of anabelian objects.
