Résumé
Abstract

Soit $p$ un nombre premier, $ℚ_{p}$ le corps des nombres $p$ -adiques et $ℂ_{p}$ la complétion d’une clôture algébrique de $ℚ_{p}$ . Dans cet article, nous obtenons un théorème de représentation pour les fonctions analytiques rigides sur $𝐏^{1} (ℂ_{p}) ∖ C (t, ϵ)$ qui sont équivariantes par le groupe de Galois $G = G a l_{c o n t} (ℂ_{p} / ℚ_{p})$ , où $t$ désigne un élément lipschitzien de $ℂ_{p}$ et $C (t, ϵ)$ un $ϵ$ -voisinage de la $G$ -orbite de $t$ .

Let $p$ be a prime number, $ℚ_{p}$ the field of $p$ -adic numbers and $ℂ_{p}$ the completion of the algebraic closure of $ℚ_{p}$ . In this paper we obtain a representation theorem for rigid analytic functions on $𝐏^{1} (ℂ_{p}) ∖ C (t, ϵ)$ which are equivariant with respect to the Galois group $G = G a l_{c o n t} (ℂ_{p} / ℚ_{p})$ , where $t$ is a lipschitzian element of $ℂ_{p}$ and $C (t, ϵ)$ denotes the $ϵ$ -neighborhood of the $G$ -orbit of $t$ .
