Demuskin groups with operators
Kay Wingberg
In this paper we consider pro-p Poincaré groups of dimension 2 (so-called Demuskin groups) on which a finite (abelian) group of order prime to p acts. In particular, we are interes…

On Cebotarev sets
Kay Wingberg
In this paper we define a topology with sufficiently good properties on the set of prime ideals of a number field.

On the Fontaine-Mazur Conjecture for CM-Fields
Kay Wingberg
Fontaine and Mazur conjecture that a number field k has no infinite unramified Galois extension such that its Galois group is a p-adic analytic pro-p-group. We consider this conjec…

Safarevic's theorem on solvable groups as Galois groups
Alexander Schmidt, Kay Wingberg
In this paper we present a complete proof of I.R.Safarevic's famous theorem that every finite solvable group occurs as a Galois group over Q.
