Structures de Hodge-Pink pour les $\varphi/\mathfrak S$-modules de Breuil et Kisin

Compositio Math. 148 (2012) 751-789 In this article, we apply the methods of our work on Fontaine's theory in equal characteristics to the $\varphi/\mathfrak S$-modules of Breuil and Kisin. Thanks to a previous article of Kisin, this yields a new and rather elementary proof of the theorem "weakly admissible implies admissible" of Colmez-Fontaine.
