Introduction. view of the goal of understanding to what extent the anabelian geometry of hyperbolic curves over p-adic local fields can be made “absolute”. Our main result . Abstract. This paper forms the first part of a three-part series in which we treat various topics in absolute anabelian geometry from the point of view of develop-.

This was proved by Mochizuki. In anabelian geometry one studies how much information about a space X X specifically: This was eventually proven by various authors in various cases.

In Uchida and Neukirch it was shown that an isomorphism between Galois groups of number fields implies the existence of an isomorphism between those number fields. From Wikipedia, anabeljan free encyclopedia.

A relation with the theory of motive s is in. This page was last edited on 25 Decemberat Florian Pop, Lectures on Anabelian phenomena in geometry and arithmetic pdf Yuri Tschinkel, Introduction to anabelian geometrytalk at Symmetries and correspondences in number theory, geometry, algebra, physics: More recently, Mochizuki introduced and developed a so called mono-anabelian geometry which restores, for a certain class of hyperbolic curves over number fields, the curve from its algebraic fundamental group.

An early conjecture motivating the theory in Grothendieck 84 was that all hyperbolic curves over number fields are anabelian varieties. Niels 3, 12 Suppose given a hyperbolic curve Geomefryi.

Retrieved from ” https: Kummer Classes and Anabelian Geometry pdf. Yuri TschinkelIntroduction to anabelian geometrytalk at Symmetries and correspondences in number theory, goemetry, algebra, physics: If you start with Szamuely as an introduction, you could then move on to this afterwards.

The classification of anabelian varieties for number fields was shown in. Isomorphisms of Galois groupsJ.

Uchida, Isomorphisms of Galois groups of algebraic function fieldsAnn. These Grothendieck conjectures were partially solved by Hiroaki Nakamura and Akio Tamagawa, geomrtry complete proofs were given by Shinichi Mochizuki. Matsumoto, Makoto, Arithmetic fundamental groups and moduli of curves. Frans Oort, Lecture notes. At MSRI, you can find some lectures from Fallincluding one specifically about anabelian geometry.

The first traditional conjectures, originating from Alexander Grothendieck and introduced in Esquisse d’un Programme were about how topological homomorphisms between two groups of two hyperbolic curves over number fields correspond to maps between the curves. Anaeblian results of mono-anabelian geometry were published in Mochizuki’s “Topics in Absolute Anabelian Geometry. A concrete example is the case of curves, which may anabelia affine as well as projective.

Grothendieck also conjectured the existence of higher-dimensional anabelian varieties, but these are still very mysterious. Jones’ theoremDeligne-Kontsevich conjecture.
