„The m-step solvable anabelian geometry of finitely generated fields“
Prof. Dr. Mohamed Saidi, University of Exeter

A celebrated theorem of Neukirch and Uchida states that the isomorphy type of a global field is functorially encoded in the isomorphy type of its absolute Galois group. The Birational anabelian Grothendieck conjecture predicts that a similar result holds for all finitely generated fields, this has been verified by Pop. In a recent joint work with Tamagawa we prove that the isomorphy type of a global field is functorially encoded in the isomorphy type of its 4-step solvable Galois group. We also prove a similar result for all finitely generated fields, in all characteristics. In my talk I will state precisely our results, review our proof in the number field case, and discuss the key ingredients of the proof in higher dimensions.
