Introduction to the paper of Ihara « Automorphisms of Pure Sphere Braid groups and Galois representations II

Gautier Ponsinet will continue the part 2 of his talkconcerning the definition and properties of the absolute Galois group of a field, the fundamental group of a topological space, and

the étale fundamental groups of schemes, which link the two previous objects.

Examples will be provided and discussed.

 

After his talk, an open discussion (debriefing and round table discussion) will take place.
