Super-Hölder vectors and the field of norms

Laurent Berger, Sandra Rozensztajn

Let E be a field of characteristic p. In a previous paper of ours, we defined and studied super-Hölder vectors in certain E-linear representations of Z_p. In the present paper, we…

Potentially semi-stable deformation rings for representations with values in $P G L_{n}$

Agnès David, Sandra Rozensztajn

We study the potentially semi-stable deformation rings for Galois representations taking their values in $P G L_{n}$ , by comparing them to the deformation rings for $G L_{n}$ . As an appli…

Decompletion of cyclotomic perfectoid fields in positive characteristic

Laurent Berger, Sandra Rozensztajn

Let $E$ be a field of characteristic $p$ . The group $Z_{p}^{\times}$ acts on $E ((X))$ by $a \cdot f (X) = f ((1 + X)^{a} - 1)$ . This action extends to the $X$ -adic completion $\tilde{…

On the locus of $2$ -dimensional crystalline representations with a given reduction modulo $p$

Sandra Rozensztajn

We consider the family of irreducible crystalline representations of dimension $2$ of $Gal (Q_{p} / Q_{p})$ given by the $V_{k, a_{p}}$ for a fixed weight integer…

An algorithm for computing the reduction of $2$ -dimensional crystalline representations of $Gal (Q_{p} / Q_{p})$

Sandra Rozensztajn

We describe an algorithm to compute the reduction modulo $p$ of a crystalline Galois representation of dimension $2$ of $Gal (Q_{p} / Q_{p})$ with dist…
