ANABELIAN GEOMETRY PDF

First page Abstract In the present paper, we study the anabelian geometry of mixedcharacteristic local fields by an algorithmic approach. We begin by discussing some generalities on log-shells of mixed-characteristic local fields. One main topic of this discussion is the difference between the log-shell and the ring of integers. Next, we consider open homomorphisms between profinite groups of MLF-type. This consideration leads us to a bi-anabelian result for absolutely unramified mixed-characteristic local fields. Next, we establish some mono-anabelian reconstruction algorithms related to each of absolutely abelian mixed-characteristic local fields, mixed-characteristic local fields of degree one, and Galois-specifiable mixed-characteristic local fields.

That is quite a list of authors. Anabelian 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.

David Corwin 6, 6 66 Anabelian geometry study materials? 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.

Anabelian geometry — Wikipedia Niels 3, 12 The book mentioned by Felipe is available here: An early conjecture motivating the theory in Grothendieck 84 was that all hyperbolic curves over number fields are anabelian varieties. A concrete example is the case of curves, which may be affine as well as projective.
