Frobenius modules and Galois representations

open access: yesAnnales de l'Institut Fourier, 2009
Frobenius modules are difference modules with respect to a Frobenius operator. Here we show that over non-archimedean complete differential fields Frobenius modules define differential modules with the same Picard-Vessiot ring and the same Galois group schemes up to extension by constants.

Artin–Schreier extensions and Galois module structure

open access: yesJournal of Number Theory, 2003
Let \(k=\mathbb F((T))\) be the field of Laurent series in \(T\) over the finite field \(\mathbb F\) of characteristic \(p>0\) and \(L\) an Artin-Schreier extension of \(k\) of degree \(p\) such that the valuation ring \(O_L\) of \(L\) is wildly ramified over \(O_k =\mathbb F[[T]]\). The author gives an \(O_k\)-basis for the associated order \(A(L/k) =

Φ-Γ-Modules for Families of Galois Representations

open access: yesJournal of Algebra, 2001
This paper shows that Fontaine's ``Linearisation Approach'' for \(Z_p\)-adic representations of an absolute local Galois group \(G_K\) carries over to a setting where the base ring \(Z_p\) is replaced by a general coefficient ring \(R\), that is, \(R\) is noetherian complete with finite residue field of characteristic \(p\).
