Abstract

These symmetry patterns are described by the absolute Galois group of the field, whose
structure is in general still a mystery.

We will describe what is known about this symmetry group: classical facts, consequences 
of the epochal work by Veovodsky and Rost, and very recent structural results and conjectures
related to higher cohomology operations and intersection theorems.
