We construct noncommutative multidimensional versions of overconvergent power series rings and Robba rings. We show that the category of étale (ϕ, Γ)-modules over certain completions of these rings are equivalent to the category of étale (ϕ, Γ)-modules over the corresponding classical overconvergent, resp. Robba rings (hence also to the cat- egory of p-adic Galois representations of Qp). Moreover, in the case of Robba rings, the assumption of étaleness is not necessary, so there exists a notion of trianguline objects in this sense.
