L’étude des systèmes dynamiques non archimédiens initiée par J. Lubin conduit à déterminer la ramification de séries à coefficients dans un corps fini , qui commutent entre elles pour la loi . Dans cet article nous traitons le cas des sous-groupes abéliens de qui correspondent par le foncteur corps de normes aux extensions abéliennes des extensions finies de , dont la ramification se stabilise dès le début.
In order to investigate the non-archimedian dynamical systems of J. Lubin, we are led to determine the ramification of series with coefficients in a finite field , which commute for the law . In this paper we study the case of abelian subgroups of which corresponds, by means of the norms field functor, to abelian extensions of finite extensions of , whose ramification is stabilized from the ground field.
