چکیده

Let K be a global eld, V an innnite proper subset of the set of all primes of K, and S a nite subset of V. Denote the maximal Galois extension of K in which each p 2 S totally splits by K tot;S. Let M be an algebraic extension of K. A data for an (S; V)-Skolem density problem for M consists of a nite subset T of V containing S, polynomials f 1 ; : : : ; f m 2 ~ KX 1 ; : : : ; X n ] satisfying jf i j q = 1 for each non-archimedean prime q 2 ~ V r ~ T , a point a 2 M n , and a positive real number. A solution to the problem is a point x 2 M n such that jx i ? a i j p < for each p 2 ~ T and jx i j q 1, jf j (x)j q = 1 for each non-archimedean prime q 2 ~

Projective extensions of fields

A field K admits proper projective extensions, i.e. Galois extensions where the Galois group is a nontrivial projective group, unless K is separably closed or K is a pythagorean formally real field without cyclic extensions of odd degree. As a consequence, it turns out that almost all absolute Galois groups decompose as proper semidirect products. We show that each local field has a unique maxi...

Global Solvably Closed Anabelian Geometry

In this paper, we study the pro-Σ anabelian geometry of hyperbolic curves, where Σ is a nonempty set of prime numbers, over Galois groups of “solvably closed extensions” of number fields — i.e., infinite extensions of number fields which have no nontrivial abelian extensions. The main results of this paper are, in essence, immediate corollaries of the following three ingredients: (a) classical ...

Heegner Points and the Rank of Elliptic Curves over Large Extensions of Global Fields

Let k be a global field, k a separable closure of k, and Gk the absolute Galois group Gal(k/k) of k over k. For every σ ∈ Gk, let k σ be the fixed subfield of k under σ. Let E/k be an elliptic curve over k. We show that for each σ ∈ Gk, the Mordell-Weil group E(k σ ) has infinite rank in the following two cases. Firstly when k is a global function field of odd characteristic and E is parametriz...

A pr 2 00 5 GALOIS MODULE STRUCTURE OF p TH - POWER CLASSES OF CYCLIC EXTENSIONS OF DEGREE

In the mid-1960s Borevič and Faddeev initiated the study of the Galois module structure of groups of pth-power classes of cyclic extensions K/F of pth-power degree. They determined the structure of these modules in the case when F is a local field. In this paper we determine these Galois modules for all base fields F . In 1947 Šafarevič initiated the study of Galois groups of maximal pextension...
