Arithmetic Breuil-Kisin-Fargues modules and several topics in p-adic Hodge theory

Heng Du (10717026) 06 May 2021 (has links)
<div> <div> <div> <p>Let K be a discrete valuation field with perfect residue field, we study the functor from weakly admissible filtered (φ,N,G<sub>K</sub>)-modules over K to the isogeny category of Breuil- Kisin-Fargues G<sub>K</sub>-modules. This functor is the composition of a functor defined by Fargues-Fontaine from weakly admissible filtered (φ,N,G<sub>K</sub>)-modules to G<sub>K</sub>-equivariant modifications of vector bundles over the Fargues-Fontaine curve X<sub>FF</sub> , with the functor of Fargues-Scholze that between the category of admissible modifications of vector bundles over X<sub>FF</sub> and the isogeny category of Breuil-Kisin-Fargues modules. We characterize the essential image of this functor and give two applications of our result. First, we give a new way of viewing the p-adic monodromy theorem of p-adic Galois representations. Also we show our theory provides a universal theory that enable us to compare many integral p-adic Hodge theories at the A<sub>inf</sub> level. </p> </div> </div> </div>

Anneaux de Fontaine et géométrie : deux exemples d'interaction / Fontaine's rings and geometry : two examples of interaction

Le Bras, Arthur-César 29 June 2017 (has links)
Cette thèse se compose de deux chapitres distincts. Les problématiques abordées y sont différentes, mais ils ont en commun de relier des objets de nature géométrique à des objets issus de la théorie de Hodge p-adique. Les résultats du premier chapitre s’inscrivent dans le cadre du programme de Langlands p-adique. Nous décrivons le complexe de de Rham des revêtements du demi-plan de Drinfeld pour GL_2(Q_p). Cette description, conjecturée par Breuil et Strauch, fournit une réalisation géométrique de la correspondance de Langlands locale $p$-adique pour certaines représentations de de Rham de dimension 2 du groupe de Galois absolu de Q_p. Le second chapitre est consacré à l’étude de la catégorie des espaces de Banach-Colmez. Notre résultat principal est une description de cette catégorie abélienne en termes de la catégorie des faisceaux cohérents sur la courbe de Fargues-Fontaine. Au passage, nous démontrons quelques résultats d’intérêt indépendant sur la cohomologie pro-étale et la cohomologie syntomique des variétés rigides. / This PhD thesis contains two chapters. The topics of these two chapters are quite different, but they have in common to draw connections between geometric objects and objects which come from p-adic Hodge theory. The framework of the first chapter is the p-adic Langlands program. We describe the de Rham complex of the étale overings of Drinfeld's p-adic upper half-plane for GL_2(Q_p). Conjectured by Breuil and Strauch, this description gives a geometric realization of the p-adic local Langlands correspondence for certain two-dimensional de Rham representations of the absolute Galois group of Q_p. The second chapter is devoted to the study of the category of Banach-Colmez spaces. Our main result is a precise description of this abelian category in terms of the category of coherent sheaves on the Fargues-Fontaine. Along the way we also prove a few results of independent interest about the pro-étale cohomology and syntomic cohomology of rigid spaces.
