Anabelian geometry

Notes, 1, Abdus Salam Int. Florian Pop, Gometry on Anabelian phenomena in geometry and arithmetic pdf Yuri Tschinkel, Introduction to anabelian geometrytalk at Symmetries and correspondences in number theory, geometry, algebra, physics: Geometgy want to study anabelian geometry, but unfortunately I’m having difficulties in finding some materials about it. In Uchida and Neukirch it was shown that an isomorphism between Galois groups gelmetry number fields implies the existence of an isomorphism between those number fields.

If you start with Szamuely as an introduction, you could then move on to this afterwards. Tannaka duality for geometric stacks. Taylor DuypuyAnabelian geometry.

Anabelian geometry is a theory in number theorywhich describes the way to which algebraic fundamental group G of a certain arithmetic variety Vor some related geometric object, can help to restore V.

For algebraic curves over finite fieldsover number fields and over p-adic field the statement was eventually completed by Mochizuki Jones’ theoremDeligne-Kontsevich conjecture. An early conjecture motivating the theory in Grothendieck 84 was that all hyperbolic curves over number fields are anabelian varieties.
