Lubin-Tate formal groups and module structure over Hopf orders
Journal de théorie des nombres de Bordeaux, Tome 11 (1999) no. 2, pp. 269-305.

Ces dernières années les ordres de Hopf ont joué dans des situations diverses un rôle important dans l'étude de la structure des module galoisiens en géométrie arithmétique. Nous introduisons ici un cadre qui rend compte des situations précédentes, et nous étudions les propriétés des algèbres de Hopf dans ce contexte général. Nous insistons en particulier sur le rôle des résolvantes dans les calculs explicites. Nous illustrons cette étude en appliquant nos résultats à la détermination de la structure de module de Hopf de l'anneau des entiers d'une extension de Lubin-Tate relative.

Over the last years Hopf orders have played an important role in the study of integral module structures arising in arithmetic geometry in various situations. We axiomatize these situations and discuss the properties of the (integral) Hopf algebra structures which are of interest in this general setting. In particular, we emphasize the role of resolvents for explicit computations. As an illustration we apply our results to determine the Hopf module structure of the ring of integers in relative Lubin-Tate extensions.
