Abstract
A fundamental idea in studying the absolute Galois group of a field is to make it act on geometric
objects such as Galois covers, étale cohomology groups and fundamental groups. The following
research topics emphasize this seminal idea: (a) Galois covers, G-torsors and their parametrizing
families, (b) motivic Galois representations, (c) anabelian towers of fundamental groups.
Striking advances have recently shed new light on the whole topic:

(c) in Anabelian Geometry: the successful introduction of methods from étale homotopy theory
(Schmidt-Stix) and from motivic A1-homotopy theory for moduli stacks of curves (Collas), the import
of operads (Fresse-Horel) which echo the Galois techniques of Pop and Hoshi-Mochizuki-Minamide,
the construction of arithmetic operads for Hurwitz moduli spaces (Westerland-Wickelgren).
