Abstract:Let K be a complete discretely valued field with mixed characteristic (0, p) and imperfect residue field k α . Let ∆ be a finite set. We construct an equivalence of categories between finite dimensional F p -representations of the product of ∆ copies of the absolute Galois group of K and multivariable étale (ϕ, Γ)-modules over a multivariable Laurent series ring over k α .Résumé ((ϕ, Γ)-modules multivariables et représentations du produit du groupe de Galois: le cas des corps résiduels imparfaits) Soit K un co… Show more
