Повний текст джерелаLet p be a prime and F be a complete discrete valuation field with a finite residual field of characteristic p. This thesis follows the p-adic and modulo p local Langlands programme which is proposed by Breuil. It consists of three chapters. Suppose moreover that F is of characteristic 0 in the first chapter and F unramified in the third. In the first chapter, we prove a part of a conjecture of Breuil and Schneider on the existence of stable lattices inside certain locally algebraic representations of \GL_n(F). In the second chapter, to an irreducible smooth representation of \GL_2(F) over \overline{\F}_p with a central character, we canonically associate a diagram which determines the isomorphism class of the original representation. In the third chapter, we use the construction of the second chapter to construct new supersingular representations in the cases considered by Breuil and Paskunas
Xu, Daxin. "Correspondances de Simpson p-adique et modulo pⁿ". Thesis, Université Paris-Saclay (ComUE), 2017. http://www.theses.fr/2017SACLS133/document.
Повний текст джерелаThis thesis is devoted to two arithmetic variants of Simpson's correspondence. In the first part, I compare the p-adic Simpson correspondence with a p-adic analogue of the Narasimhan-Seshadri's correspondence for curves over p-adic fields due to Deninger and Werner. Narasimhan and Seshadri established a correspondence between stable bundles of degree zero and unitary representations of the topological fundamental group for a complex smooth proper curve. Using parallel transport, Deninger and Werner associated functorially to every vector bundle on a p-adic curve whose reduction is strongly semi-stable of degree 0 a p-adic representation of the fundamental group of the curve. They asked several questions: whether their functor is fully faithful; whether the cohomology of the local systems produced by this functor admits a Hodge-Tate filtration; and whether their construction is compatible with the p-adic Simpson correspondence developed by Faltings. We answer positively these questions. The second part is devoted to the construction of a lifting of the Cartier transform of Ogus-Vologodsky modulo pⁿ. Let W be the ring of the Witt vectors of a perfect field of characteristic p, X a smooth formal scheme over W, X' the base change of X by the Frobenius morphism of W, X'_2 the reduction modulo p² of X' and Y the special fiber of X. We lift the Cartier transform of Ogus-Vologodsky relative to X'_2 modulo pⁿ. More precisely, we construct a functor from the category of pⁿ-torsion O_{X'}-modules with integrable p-connection to the category of pⁿ-torsion O_X-modules with integrable connection, each subject to a suitable nilpotence condition. Our construction is based on Oyama's reformulation of the Cartier transform of Ogus-Vologodsky in characteristic p. If there exists a lifting F: X -> X' of the relative Frobenius morphism of Y, our functor is compatible with a functor constructed by Shiho from F. As an application, we give a new interpretation of relative Fontaine modules introduced by Faltings and of the computation of their cohomology

Повний текст джерелаIn this thesis we study the p-adic properties of P.E.L. type Shimura varieties which have good reduction at p and for which the ordinary locus is empty. In the first chapter, we construct locally some invariants that cuts out inside the Shimura varieties an open and dense locus, the mu-ordinary locus, and study the geometric properties of these invariants. In the second chapter we extend to the unramified mu-ordinary case the theory of the canonical subgroup. Thus, we construct for ’nearly’ mu-ordinary families of p-divisible groups a canonical filtration of the p^n-torsion. This applies in particular to some strict rigid neighbourhoods of the mu-ordinary locus of the Shimura varieties previously studied. In the third chapter, which is a collaboration with Stéphane Bijakowski, we extend the construction of the invariants of the first chapter to some local integral models of Shimura varieties where the prime p can be ramified in the local datum. Finally, in the last chapter, we use the constructions of the first two chapter to construct a rigid variety, the Eigenvariety, which parametrises the finite slope p-adic families of Picard automorphic forms when the prime p is inert in the quadratic imaginary field of the Picard datum
Le, Bras Arthur-César. "Anneaux de Fontaine et géométrie : deux exemples d'interaction." Thesis, Paris 6, 2017. http://www.theses.fr/2017PA066020.
Повний текст джерелаThis 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
Bouis, Tess. "On the motivic cohomology of mixed characteristic schemes." Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPASM033.
Повний текст джерелаIn this thesis, we construct a theory of motivic cohomology for quasi-compact quasi-separated schemes, which generalises the construction of Elmanto-Morrow in the case of schemes over a field. Our construction is non-A¹-invariant in general, but it uses the classical A¹-invariant motivic cohomology of smooth ℤ-schemes as an input. The main new input of our construction is a global filtration on topological cyclic homology, whose graded pieces provide a common generalisation of derived de Rham cohomology and Bhatt-Morrow-Scholze's syntomic cohomology. Our theory satisfies various expected properties of motivic cohomology, including a relation to non-connective algebraic K-theory via an Atiyah-Hirzebruch spectral sequence, the projective bundle formula, and pro cdh descent. The results of Chapter 11 have appeared as [Bou23]

Повний текст джерелаUnder a few assumptions, we prove an equivalence of category between a subcategory of F-isocristals on a smooth algebraic variety and overcongergent integrable De Rham-Witt connections. We do so by giving an equivalent definition of overconvergence, and by studying the explicit local structure of the De Rham-Witt complex

Повний текст джерелаThis thesis is devoted to further developing the program of geometrization of the local p-adic Langlands correspondence, which was initiated by Colmez, Dospinescu and Niziol in their 2020 paper. They have shown that 2-dimensional Galois representations that are supercuspidal (implicitly de Rham) and with Hodge-Tate weights 0 and 1, appear in the p-adic étale cohomology of the coverings of Drinfeld's half-plane and that their multiplicity is given by the p-adic Langlands correspondence. The main result of this thesis is the generalization of this result in arbitrary weights, by considering the p-adic étale cohomology with coefficients in the symmetric powers of the universal local system on Drinfeld's tower. A striking novelty is the appearance of special representations in the cohomology of the tower with coefficients, with expected multiplicity. The key point is that the local systems which we consider turn out to be particularly simple: they are isotrivial opers.The first part of this thesis is devoted to the study of local isotrivial p-adic systems and to the calculation, in the case of isotrivial opers on curves, of a diagram linking the proetale cohomology of the local system to the Hyodo-Kato cohomology and the de Rham cohomology of the curve.The second part of this thesis is the application of these results to the case of the Drinfeld's tower, allowing the computation of the mentioned multiplicities

Повний текст джерелаThe theory of arithmetic D-modules was developed by Pierre Berthelot, based on the main ideas of Grothendieck and Mebkhout, who were the first to see the D-modules as a new cohomological approach. The primary aim of my thesis was to generalize the local descriptions of arithmetic D-modules in the smooth case, found by Pierre Berthelot. We want to integrate recent case studies, in particular from Richard Crew, where he studies formally smooth schemes. For that purpose, we generalize the notion of relatively perfect to the cases of formal schemes and obtain in this context a similar description to the smooth case. In a second step, we give an algorithm which allows calculating the zeta function of certain varieties, which are the extension of a variety that is already known to calculate the zeta function
Chatel, Gweltaz. "Comptage de points : application des méthodes cristallines." Rennes 1, 2007. http://www.theses.fr/2007REN1S023.
Повний текст джерелаWe deal in this thesis with the computation of the number of points of algebraic curves over finite fields. By use of the stability of the rigid cohomology with compact support by finite etale descent, we show that the computation of the cohomology groups of such a curve can be reduced to the computation of the cohomology groups of an isocrystal over an open subset of the affine line and we build an algorithm achieving this operation in polynomial time. We then show that using a lifting of Frobenius for an algebraic curve over a finite field computed thanks to an algorithm presented by Gerkmann in his thesis, we can count the number of points of the curve by application of the trace formula for rigid cohomology, finally obtaining a polynomial time algorithm working for a large class of curves. We furthermore find complexities for our algorithms, using some technics introduced by Lauder in order to control the absolute value of the elements of the cohomology basis we handle
Deng, Taiwang. "Induction parabolique et géométrie des variétés orbitales pour GLn." Thesis, Sorbonne Paris Cité, 2016. http://www.theses.fr/2016USPCD070/document.
Повний текст джерелаAriki and Ginzburg, after the previous work of Zelevinsky on orbital varieties,proved that multiplicities in a total parabolically induced representations aregiven by the value at q = 1 of Kazhdan-Lusztig Polynomials associated to thesymmetric groups. In my thesis I introduce the notion of partial derivativewhich refines the Zelevinsky derivative and show that it can be identified withthe formal exponential of the q-derivative of Kashiwara with q=1. With thehelp of this notion, I exploit the geometry of the nilpotent orbital varietiesto construct a symmetrization process for the multi-segments, which allowsme to proove a conjecture of Zelevinsky on the property of the independenceof the total parabolic induction. On the other hand, I develop a strategyto calculate the multiplicity in a general parabolic induction by using theLusztig product of perverse sheaves

Повний текст джерелаThis thesis deals with the arithmetic of linear groups over p-adic function fields. We divide the thesis into several parts.In the first part, we recall a cohomological obstruction to the Hasse principle for torsors under tori [HS16] and another obstruction to weak approximation for tori [HSS15] Subsequently we compare the two obstructions in two different manners. In particular, we show that the obstruction to the Hasse principle for torsors under tori can be described by an unramifed cohomology group.In the second part, we establish some arithmetic duality theorems and deduce a Poitou-Tate style exact sequence for a short complex of tori. Later on, we manage to find a defect to weak approximation for certain connected reductive groups using a piece of the Poitou-Tate sequence.In the last part, we consider a Borel-Serre style finiteness theorem in Galois cohomology. The first ingredient is that the finiteness of the kernel of the global-to-local map for linear groups will follow from that of absolutely simple simply connected groups. Subsequently, we show the kernel is a finite set for a list of absolutely simple simply connected groups

Повний текст джерелаThis thesis concerns the pro-unipotent fundamental group of the projective line minus three points, defined by Deligne in 1989. We consider more specifically its cristalline Frobenius and its "Knizhnik-Zamolodchikov" connection. The goal is to understand its p-adic periods, that is to say the p-adic analogues of multiple zeta values. The study also leads to a notion of "finite multiple zeta values" ; it enlightens another notion of finite multiple zeta values defined by Zagier in 2011. The parts I and II concern p-adic multiple zeta values. We give several ways, one "direct" (part I) and two "indirect" (part II), to compute them. It enables to discover as well certain properties of multiple harmonic sums. The part II leads to, among other things, the definition of the notion of finite multiple zeta values evoked above. These are elements of the product of all Zp's ; they can be expressed in terms of p-adic multiple zeta values, and vice versa. They must be seen as a substitute to p-adic multiple zeta values, which have the advantage to be given by very simple explicit formulas, and whose properties reflect those of p-adic multiple zeta values. The part III is mostly a study of the algebraic properties of finite multiple zeta values, and of other related numbers. We justify the statement that they are variants of multiple zeta values, by showing that they satisfy variants of the standard algebraic properties of multiple zeta values. At the end of part III, we obtain a new series expansion of p-adic zeta values. The three parts also contain other annex results
Junger, Damien. "Cohomologies p-adiques et espaces de Rapoport-Zink." Thesis, Lyon, 2020. https://tel.archives-ouvertes.fr/tel-03172041.
Повний текст джерелаThis thesis studies the geometry and the cohomology of the Drinfeld symmetric space and its coverings. It has been shown that the supercuspidal part of the l-adic cohomology of this spaces provides a geometric realization of the local Langlands and the Jacquet-Langlands correspondence. Following the methods in the thesis of Wang Hoaran, we establish the same correspondances for the De Rham cohomology (forgetting the action of the Weil group) for the first covering. For that matter, we need to generalize a result of Grosse-Klönne on the De Rham cohomology of analytic spaces admitting a semi-stable model.We also need some informations on the level 0. In particular, we compute the invertible functions on the Drinfeld space. Indeed, we have stronger result where we compute the whole analytic cohomology on the sheaf of invertible function (all these calculations are done in the more general context of hyperplan arrangement). This allow us to give an explicit equation for the first covering essential for the computation of De Rham cohomology

Повний текст джерелаLiu, Junjiang. "On p-adic decomposable form inequalities." Thesis, Bordeaux, 2015. http://www.theses.fr/2015BORD0258/document.
Повний текст джерелаLet F ∈ Z[X1, . . . ,Xn] be a decomposable form, that is, a homogeneous polynomial of degree d which can be factored into linear forms over C. Denote by NF (m) the number of integer solutions to the inequality |F(x)| ≤ m and by VF (m) the volume of the set{x ∈ Rn : |F(x)| ≤ m}. In 2001, Thunder [19] proved a conjecture of W.M. Schmidt, stating that, under suitable finiteness conditions, one has NF (m) << mn/d where the implicit constant depends only on n and d. Further, he showed an asymptotic formula NF (m) = mn/dV (F) + OF (mn/(d+n−2)) where, however, the implicit constant depends on F. In subsequent papers, Thunder’s concern was to obtain a similar asymptotic formula, but with the upper bound of the error term |NF (m)−mn/dV (F)| depending only on n and d. In [20] and [22], hemanaged to prove that if gcd(n, d) = 1, the implicit constant in the error term can indeed be made depending only on n and d.The main objective of this thesis is to extend Thunder’s results to the p-adic setting. Namely, we are interested in solutions to the inequality |F(x)| · |F(x)|p1 . . . |F(x)|pr ≤ m in x = (x1, x2, . . . ,xn) ∈ Zn with gcd(x1, x2, . . . ,xn, p1 · · · pr) = 1. (5.4.3)where p1, . . . , pr are distinct primes and | · |p denotes the usual p-adic absolute value.Chapter 1 is devoted to the p-adic set-up of this problem and to the proofs of the auxiliary lemmas. Chapter 2 is devoted to extending Thunder’s results from [19]. In chapter 3, we show the effectivity of the condition under which the number of solutions of (5.4.3) is finite. Chapter 4 and chapter 5 generalize Thunder’s results from [20], [21] and [22]

Повний текст джерелаIn this thesis, we study constructibility problems in non-Archimedean analytic geometry over a non-Archimedean field k. We study some subsets (semianalytic, subanalytic. . . ) in the framework of k-analytic spaces, whereas until now they had only been consider as subsets of rigid k-spaces. \par We especially study subanalytic (and overconvergent subanalytic) sets using non-rigid points of Berkovich spaces. With this, we give new proofs of prior results, establish some new properties and clarify a mistake concerning the local behaviour of overconvergent subanalytic sets which had not been noticed until now. \par We also give finiteness results for compactly supported cohomology of germs H^q_c((\X^\an,S) , \Q_l) where S is a locally closed semi-algebraic subset of the analytification of some algebraic k-variety \X. Finally, we generalize some results about tropicalization maps of compactk-analytic spaces

Повний текст джерелаThis PhD thesis deals with some particular aspects of the algebraic systems resolution. Firstly, we introduce a way of minimizing the number of additive variables appearing in an algebraic system. For this, we make use of two invariants of variety introduced by Hironaka: the ridge and the directrix. Then, we propose fast arithmetic routines, the so-called relaxed routines, for p-adic integers. These routines allow us, then, to solve efficiently an algebraic system with rational coefficients locally, i. E. Over the p-adic integers. In a fourth part, we are interested in the factorization of a bivariate polynomial, which is at the root of the decomposition of hypersurfaces into irreducible components. We propose an algorithm reducing the factorization of the input polynomial to that of a polynomial whose dense size is essentially equivalent to the convex-dense size of the input polynomial. In the last part, we consider real algebraic systems solving in average. We design a probabilistic algorithm computing an approximate complex zero of the real algebraic system given as input

Повний текст джерелаIn a first part, we compare Bushnell-Kutzko's and Yu's constructions of supercuspidal representations. In a tame situation, at each step of Bushnell-Kutzko's construction, we associated a part of a Yu datum. We finally get a link between these constructions when they are both defined: GLN in the tame case. In a second part we define analytic filtrations. For any rational point x in the reduced Bruhat-Tits building of G and any positive rational number r, we introduce a k-affinoid groupGₓ,ᵣ contained in the Berkovich analytification Gªⁿ of G. The Shilov boundary of Gₓ,ᵣ is a singleton. In this way we obtain a topological cone, whose basis is the reduced Bruhat-Tits building and vertex the neutral element, inside Gªⁿ parametrizing the k-affinoid groups Gₓ,ᵣ. We also define filtrations for the Lie algebra. We state and prove various properties of analytic filtrations and compare them with Moy-Prasad ones

Elle jouit de propriétés semblables à celles des espaces analytiques complexes d'un point de vue topologique, mais également algébrique, son faisceau structural étant cohérent. En outre, en termes cohomologiques, ses disques se comportent comme des espaces de Stein.
Pour finir, nous exposons quelques applications des résultats géométriques énoncés auparavant. Nous obtenons ainsi quelques propriétés de classes de fonctions particulières, telles les fonctions holomorphes sur un disque contenu dans C et dont le développement en un point est à coefficients entiers.
