Bockstein Spectral Sequences and Applications to the Tame Fontaine Mazur Conjecture

Julian Feuerpfeil

For a number field $K$ , a prime $p$ and a finite set of tame places $S$ we consider the groups $G_{K, S}$ - the Galois groups of the maximal pro- $p$ extension of $K$ unramified outs…

A cohomological translation of the Kaplansky radical for profinite groups

Simone Blumer, Julian Feuerpfeil, Lucas Correa Lopes +1

The Kaplansky radical of a field consists of the nonzero elements represented by every norm quadratic form in two variables. D. Kijima and M. Nishi conjectured that, for quadratic…

On the Bogomolov-Positselski Conjecture

Julian Feuerpfeil

Let $p$ be a prime. An oriented pro- $p$ group $(G, θ)$ is said to have the Bogomolov--Positselski property if it is Kummerian and if $I_{θ} (G)$ is a free pro- $p$ group. In this paper,…
