Wald, Christian. « A p-adic quantum group and the quantized p-adic upper half plane ». Doctoral thesis, Humboldt-Universität zu Berlin, 2017. http://dx.doi.org/10.18452/18201.
Texte intégralA quantum group is a noncommutative noncocommutative Hopf algebra. In this thesis we deform the locally convex Hopf algebra of locally analytic functions on GL(2,O), where O is the valuation ring of a finite extension of the p-adic numbers. We show that this deformation is a noncommutative noncocommutative locally convex Hopf algebra, i.e. a p-adic quantum group. Our main result is that the strong dual of our deformation is a Fréchet Stein algebra, i.e. a projective limit of Noetherian Banach algebras with right flat transition maps. This was shown in the commutative case by P. Schneider and J. Teitelbaum. For our proof in the noncommutative case we use ideas of M. Emerton, who gave an alternative proof of the Fréchet Stein property in the commutative case. For the proof we describe completions of the quantum enveloping algebra and use partial divided powers. An important class of locally analytic representations of GL(2,K) is constructed from global sections of line bundles on the p-adic upper half plane. We construct a noncommutative analogue of an affine version of the p-adic upper half plane which we expect to give rise to interesting representations of our p-adic quantum group. We construct this space by using the Manin quantum plane, the Bruhat-Tits tree for PGL(2,K) and the theory of algebraic microlocalization.

Texte intégralThis thesis is divided in 8 chapters. Chapter ref{chapterpreliminaries} is of preliminary nature: we recall the tools that we will use in the rest of the thesis and some previously known results. Chapter ref{chapterpresentation} is devoted to summarize in a uniform way the new results obtained in this thesis.The other six chapters are original. In Chapters ref{chapterUOIp} and ref{chapterneron}, we prove the following: given a smooth proper morphism $f:Yrightarrow X$ over a smooth geometrically connected base $X$ over an infinite finitely generated field of positive characteristic, there are lots of closed points $xin |X|$ such that the rank of the N'eron-Severi group of the geometric fibre of $f$ at $x$ is the same of the rank of the N'eron-Severi group of the geometric generic fibre. To prove this, we first study the specialization of the $ell$-adic lisse sheaf $R^2f_*Ql(1)$ ($ellneq p$), then we relate it with the specialization of the F-isocrystal $R^2f_{*,crys}mathcal O_{Y/K}(1)$ passing trough the category of overconvergent F-isocrystals. Then, the variational Tate conjecture in crystalline cohomology, allows us to deduce the result on the N'eron-Severi groups from the results on $R^2f_{*,crys}mathcal O_{Y/K}(1)$. These extend to positive characteristic results of Cadoret-Tamagawa and Andr'e in characteristic zero.Chapters ref{chaptermarcuzzo} and ref{chapterpadic} are devoted to the study of the monodromy groups of (over)convergent F-isocrystals. Chapter ref{chaptermarcuzzo} is a joint work with Marco D'Addezio. We study the maximal tori in the monodromy groups of (over)convergent F-isocrystals and using them we prove a special case of a conjecture of Kedlaya on homomorphism of convergent $F$-isocrystals. Using this special case, we prove that if $A$ is an abelian variety without isotrivial geometric isogeny factors over a function field $F$ over $overline{F}_p$, then the group $A(F^{mathrm{perf}})_{tors}$ is finite. This may be regarded as an extension of the Lang--N'eron theorem and answer positively to a question of Esnault. In Chapter ref{chapterpadic}, we define $overline Q_p$-linear category of (over)convergent F-isocrystals and the monodromy groups of their objects. Using the theory of companion for overconvergent F-isocrystals and lisse sheaves, we study the specialization theory of these monodromy groups, transferring the result of Chapter ref{chapterUOIp} to this setting via the theory of companions.The last two chapters are devoted to complements and refinement of the results in the previous chapters. In Chapter ref{chaptertate}, we show that the Tate conjecture for divisors over finitely generated fields of characteristic $p>0$ follows from the Tate conjecture for divisors over finite fields of characteristic $p>0$. In Chapter ref{chapterbrauer}, we prove uniform boundedness results for the Brauer groups of forms of varieties in positive characteristic, satisfying the $ell$-adic Tate conjecture for divisors. This extends to positive characteristic a result of Orr-Skorobogatov in characteristic zero

Let G be a split, semisimple p-adic group. We construct a derived localization functor Loc : ... from the compactified category of [BK2] associated to G to the category of equivariant sheaves on the Bruhat-Tits building whose stalks have finite-multiplicity isotypic components as representations of the stabilizer. Our construction is motivated by the "coherent-constructible correspondence" functor in toric mirror symmetry and a construction of [CCC]. We show that Loc has a number of useful properties, including the fact that the sections ... compactifying the finitely-generated representation V. We also construct a depth = e "truncated" analogue Loc(e) which has finite-dimensional stalks, and satisfies the property RIP ... V of depth = e. We deduce that every finitely-generated representation of G has a bounded resolution by representations induced from finite-dimensional representations of compact open subgroups, and use this to write down a set of generators for the K-theory of G in terms of K-theory of its parahoric subgroups.

Texte intégralSchoemann, Claudia. « Représentations unitaires de U(5) p-adique ». Thesis, Montpellier 2, 2014. http://www.theses.fr/2014MON20101.
Texte intégralWe study the parabolically induced complex representations of the unitary group in 5 variables - U(5)- defined over a non-archimedean local field of characteristic 0. This is Qp or a finite extension of Qp ,where p is a prime number. We speak of a 'p-adic field'.Let F be a p-adic field. Let E : F be a field extension of degree two. Let Gal(E : F ) = {id, σ}. We write σ(x) = overline{x} forall x ∈ E. Let | |p denote the p-adic norm on E. Let E* := E {0} and let E 1 := {x ∈ E | x overline{x} = 1} .U(5) has three proper parabolic subgroups. Let P0 denote the minimal parabolic subgroup and P1 andP2 the two maximal parabolic subgroups. Let M0 , M1 and M2 denote the standard Levi subgroups and let N0 , N1and N2 denote unipotent subgroups of U(5). One has the Levi decomposition Pi = Mi Ni , i ∈ {0, 1, 2} .M0 = E* × E* × E 1 is the minimal Levi subgroup, M1 = GL(2, E) × E 1 and M2 = E* × U (3) are the two maximal parabolic subgroups.We consider representations of the Levi subgroups and extend them trivially to the unipotent subgroups toobtain representations of the parabolic groups. One now performs a procedure called 'parabolic induction'to obtain representations of U (5).We consider representations of M0 , further we consider non-cuspidal, not fully-induced representationsof M1 and M2 . For M1 this means that the representation of the GL(2, E)− part is a proper subquotientof a representation induced from E* × E* to GL(2, E). For M2 this means that the representation of theU (3)− part of M2 is a proper subquotient of a representation induced from E* × E 1 to U (3).As an example for M1 , take | det |α χ(det) StGL2 * λ' , where α ∈ R, χ is a unitary character of E* , StGL2 is the Steinberg representation of GL(2, E) and λ' is a character of E 1 . As an example forM2 , take | |α χ λ' (det) StU (3) , where α ∈ R, χ is a unitary character of E* , λ' is a character of E 1 andStU (3) is the Steinberg representation of U (3). Note that λ' is unitary.Further we consider the cuspidal representations of M1 .We determine the points and lines of reducibility of the representations of U(5), and we determinethe irreducible subquotients. Further, except several particular cases, we determine the unitary dual ofU(5) in terms of Langlands-quotients.The parabolically induced complex representations of U(3) over a p-adic field have been classied byCharles David Keys in [Key84], the parabolically induced complex representations of U(4) over a p-adicfield have been classied by Kazuko Konno in [Kon01].An aim of further study is the classication of the induced complex representations of unitary groupsof higher rank, like U (6) or U (7). The structure of the Levi subgroups of U (6) resembles the structureof the Levi subgroups of U (4), the structure of the Levi groups of U (7) resembles those of U (3) and ofU (5).Another aim is the classication of the parabolically induced complex representatioins of U (n) over ap-adic field for arbitrary n. Especially one would like to determine the irreducible unitary representations

Texte intégralLet G be a compact p-adic analytic group with no element of order p such that it is the direct sum of a torsion free compact p-adic analytic group H whose Lie algebra is split semisimple and an abelian p-adic analytic group Z of dimension n. In chapter 3, we show that if M is a finitely generated torsion module over the Iwasawa algebra of G with no non-zero pseudo-null submodule, then the image q(M) of M via the quotient functor q is completely faithful if and only if M is torsion free over the Iwasawa algebra of Z. Here the quotient functor q is the unique functor from the category of modules over the Iwasawa algebra of G to the quotient category with respect to the Serre subcategory of pseudo-null modules. In chapter 4, we show the following: Let M, N be two finitely generated modules over the Iwasawa algebra of G such that they are objects of the category Q of those finitely generated modules over the Iwasaw algebra of G which are also finitely generated as modules over the Iwasawa algebra of H. Assume that q(M) is completely faithful and [M] =[N] in the Grothendieck group of Q. Then q(N) is also completely faithful. In chapter 6, we show that if G is any compact p-adic analytic group with no element of order p, then the Grothendieck groups of the algebras of continuous distributions and bounded distributions are isomorphic to c copies of the ring of integers where c denotes the number of p-regular conjugacy classes in the quotient group of G with an open normal uniform pro-p subgroup H of G.

Texte intégralInspired by the conjecture of local Langlands in families of Dat, Helm, Kurinczuk and Moss, for a connected reductive group G defined over F_q, we study the relations of the following three rings: (i) the Z-model E_G of endomorphism algebras of Gelfand–Graev representations of G(F_q); (ii) the Grothendieck ring K_{G*} of the category of representations of G*(F_q) of finite dimension over F_q, with G* the Deligne–Lusztig dual of G; (iii) the ring of functions B_{G^vee} of (T^vee // W)^{F^vee}, with G^vee the Langlands dual (defined and split over Z) of G. We show that Z[1/pM]E_G simeq Z[1/pM]K_{G*} as Z[1/pM]-algebras with p = char(F_q) and M the product of bad primes for G, and that K_{G*} simeq B_{G^vee} as rings when the derived subgroup of G^vee is simply-connected. Benefiting from these results, we then give an explicit description of the unipotent l-block of p-adic GL_2 with l different from p. The material of this work, except for § 4, mainly originates from my article [Li2] and from my other article [LiSh] in collaboration with J. Shotton

Texte intégralCette thèse traite deux problèmes concernant la théorie des représentations l-modulaires d’un groupe p-adique. Soit F un corps local non archimédien de caractéristique résiduelle p différente de l. Dans la première partie, on étudie la décomposition en blocs de la catégorie des représentations lisses `-modulaires de GL(n; F) et de ses formes intérieures. On veut ramener la description d’un bloc de niveau positif à celle d’un bloc de niveau 0 (d’un autre groupe du même type) en cherchant des équivalences de catégories. En utilisant la théorie des types de Bushnell-Kutzko dans le cas modulaire et un théorème de la théorie des catégories, on se ramene à trouver un isomorphisme entre deux algèbres d’entrelacement. La preuve de l’existence d’un tel isomorphisme n’est pas complète car elle repose sur une conjecture qu’on énonce et qui est prouvée pour plusieurs cas. Dans une deuxième partie on généralise la construction du groupe métaplectique et de la représentation de Weil dans le cas des représentations sur un anneau intègre. On construit une extension centrale du groupe symplectique sur F par le groupe multiplicatif d’un anneau intègre et on prouve qu’il satisfait les mêmes propriétés que dans le cas des représentations complexes.
Nguyen, Manh Tu. « Higher Hida Theory on Unitary Group GU (2,1) ». Thesis, Lyon, 2020. http://www.theses.fr/2020LYSEN009.
Texte intégralIn their breakthrough work, Calegari and Geraghty have shown how to bypass some serious restrictions of the original method by Taylor-Wiles, thus allowing us to attack more general modularity conjectures and related questions. Their method hinges on two conjectures, one is related to the problem of attaching Galois representations to torsion classes in the cohomology of Shimura varieties and the other to the requirement that these cohomology groups, localised at an appropriate ideal are non zero only in a certain range. The first conjecture is addressed in a great generality by Peter Scholze, but the second remains elusive. Recently, for coherent cohomology, inspired by the classical Hida theory, Vincent Pilloni has proposed a method consisting of p-adically interpolating the entire complex of coherent sheaves of automorphic forms on the Siegel threefold. This serves as a way to get around the second conjecture above and plays a crucial role in a recent work, where they show that abelian surfaces over a totally real field are potentially modular. In this thesis, we adapt the argument of Pilloni to construct a Hida complex interpolating classes in higher cohomology groups of the Picard modular surface. In a future work, we hope to use this to obtain some similar modularity results for abelian three-folds arising as Jacobians of some Picard curves

Texte intégralThis thesis is a contribution to the study of p-adic (i.e. unitary continuous on p-adic Banach spaces) and mod p (i.e. smooth over a finite field of characteristic p) representations of a split p-adic reductive group G.We determine the extensions between p-adic and mod p principal series of G. In order to do so, we compute Emerton's delta-functor H•OrdB of derived ordinary parts with respect to a Borel subgroup on a principal series using a Bruhat filtration.We also determine the extensions of a principal series by an ordinary representation (i.e. parabolically induced from a special representation of the Levi twisted by a character), as well as the Yoneda extensions of higher length between mod p principal series under a conjecture of Emerton true for GL2.Moreover, we show that there exists no “chain” of three distinct p-adic or mod p principal series of G. In order to do so, we partially compute the delta-functor H•OrdP with respect to any parabolic subgroup on a principal series. Exploiting this result, we prove a conjecture of Breuil and Herzig on the uniqueness of certain p-adic representations of G whose constituents are principal series, as well as its mod p analogue.Finally, we formulate a new conjecture on the extensions between irreducible mod p representations of G parabolically induced from a supersingular representation of the Levi. We prove this conjecture for extensions by a principal series

Texte intégralA key tool in p-adic representation theory is the Iwasawa algebra, originally constructed by Iwasawa in 1960's to study the class groups of number fields. Since then, it appeared in varied settings such as Lazard's work on p-adic Lie groups and Fontaine's work on local Galois representations. For a prime p, the Iwasawa algebra of a p-adic Lie group G, is a non-commutative completed group algebra of G which is also the algebra of p-adic measures on G. It is a general principle that objects coming from semi-simple, simply connected (split) groups have explicit presentations like Serre's presentation of semi-simple algebras and Steinberg's presentation of Chevalley groups as noticed by Clozel. In Part I, we lay the foundation by giving an explicit description of certain Iwasawa algebras. We first find an explicit presentation (by generators and relations) of the Iwasawa algebra for the principal congruence subgroup of any semi-simple, simply connected Chevalley group over Z_p. Furthermore, we extend the method to give a set of generators and relations for the Iwasawa algebra of the pro-p Iwahori subgroup of GL(n,Z_p). The base change map between the Iwasawa algebras over an extension of Q_p motivates us to study the globally analytic p-adic representations following Emerton's work. We also provide results concerning the globally analytic induced principal series representation under the action of the pro-p Iwahori subgroup of GL(n,Z_p) and determine its condition of irreducibility. In Part II, we do numerical experiments using a computer algebra system SAGE which give heuristic support to Greenberg's p-rationality conjecture affirming the existence of "p-rational" number fields with Galois groups (Z/2Z)^t. The p-rational fields are algebraic number fields whose Galois cohomology is particularly simple and they offer ways of constructing Galois representations with big open images. We go beyond Greenberg's work and construct new Galois representations of the absolute Galois group of Q with big open images in reductive groups over Z_p (ex. GL(n, Z_p), SL(n, Z_p), SO(n, Z_p), Sp(2n, Z_p)). We are proving results which show the existence of p-adic Lie extensions of Q where the Galois group corresponds to a certain specific p-adic Lie algebra (ex. sl(n), so(n), sp(2n)). This relates our work with a more general and classical inverse Galois problem for p-adic Lie extensions
Szumowicz, Anna Maria. « Regular representations of GLn( O) and the inertial Langlands correspondence ». Thesis, Sorbonne université, 2019. http://www.theses.fr/2019SORUS360.
Texte intégralThis thesis is divided into two parts. The first one comes from the representation theory of reductive p-adic groups. The main motivation behind this part of the thesis is to find new explicit information and invariants of the types in general linear groups. Let F be a nonArchimedean local field and let OF be its ring of integers. We give an explicit description of cuspidal types on GLp(OF ), with p prime, in terms of orbits. We determine which of them are regular representations and we provide an example which shows that an orbit of a representation does not always determine whether it is a cuspidal type or not. At the same time we prove that a cuspidal type for a representation π of GLp(F) is regular if and only if the normalised level of π is equal to m or m − 1 p for m ∈ Z. The second part of the thesis comes from the theory of integer-valued polynomials and simultaneous p-orderings. This is a joint work with Mikołaj Frączyk. The notion of simultaneous p-ordering was introduced by Bhargava in his early work on integer-valued polynomials. Let k be a number field and let Ok be its ring of integers. Roughly speaking a simultaneous p-ordering is a sequence of elements from Ok which is equidistributed modulo every power of every prime ideal in Ok as well as possible. Bhargava asked which subsets of Dedekind domains admit simultaneous p-ordering. Together with Mikołaj Frączyk we proved that the only number field k with Ok admitting a simultaneous p-ordering is Q

Let G be a connected reductive group with a split maximal torus defined over a nonarchimedean local field. I evaluate a matrix coefficient of the unramified principal series of G known as the "Bessel function" at torus elements of dominant coweight. I show that the Bessel function shares many properties with the Macdonald spherical function of G, in particular the properties described in Casselman's 1980 evaluation of that function. The analogy I demonstrate between the Bessel and Macdonald spherical functions extends to an analogy between the spherical Whittaker function, evaluated by Casselman and Shalika in 1980, and a previously unstudied matrix coefficient.

Texte intégralThis thesis consists of two parts: the first one gives a generalization of fiber spaces constructed above the Bruhat-Tits tree of the group GL(2) over a p-adic field. More precisely we construct a projective tower of spaces over the 1-skeleton of the Bruhat-Tits building of GL(n) over a p-adic field. We show that any cuspidal representation π of GL(n) embeds with multiplicity 1 in the first cohomology space with compact support of k-th floor of the tower, where k is the conductor of π. In the second part we constructed a space W above the barycentric subdivision of the Bruhat-Tits building of GL(n) over a p-adic field. To study the cohomology spaces with compact support of a proper G-simplicial complex X with a rather special equivariant covering, where G is a totally disconnected locally compact group, we show the existence of a spactrale sequence in the category of smooth representations of G that converges to the cohomology with compact support of X. Based on the latter results, we calculate the cohomology with compact support of W as smooth representation of GL(n), and then we show that the level zero cuspidal types of GL(n) appear with finite multiplicity in the cohomology of some finite simplicial complexes constructed in residual level. As a consequence, we show that the cuspidal representations of level 0 of GL(n) appear in the cohomology of W

Texte intégralThis thesis is dedicated to the study of linear definable groups in p-adic fields. Ani-sotropic tori play an important role in this work. We give a model-theoretic andalgebraic description of anisotropic Qp-tori of dimension 1.The study of Cartan subgroups in SL2(Qp) (where Qp is a field elementarily equi-valent to Qp) permit us to give a complete description of all definable subgroups ofSL2(Qp).We are seeing also linear groups definable in p-minimal expansions of p-adically closedfields. We introduce a notion of p-connexity for groups. We etablish that every linearcommutative p-connected group definable in such structure is isomorphic to a semi-algebraic group.Finally some results on genericity and generosity in SL2(Qp) are given

Texte intégralIn this thesis, we show tow results of Harmonic Analysis on réductive p-adic group.The first results extends the matrix Paley-Wiener theorem to the non-connected case. Let G be reductive (non necessarily connected) p-adic group. The Hecke algebra of compactly supported locally constant complex functions on G acts on complex smooth irreducible representations of G. The action of a given function is seen as its Fourier transform. The theorem characterizes the image of the Hecke algebra under the Fourier transform and provides an inversion formula.The second result is the proof of a spectral identity on the so-called twisted GLn group (where n is even, on a p-adic field) for the twisted orbital integral over the twisted stable conjugacy class of antisymetric invertible matrices. We express it as an integral over those irreducible tempered auto-dual representations of GLn whose Langlands' parameter is symplectic. Our proof uses endoscopic transfer

Texte intégralLet F be a nonarchimedean locally compact field of residue characteristic p and let D be a finite dimensional central division algebra over F. Let m be a stricly positive integer. We study the category R of smooth finite length representations of Glm(D) on a field of characteristic l, with l not equal to p, and the aim is to find a block decomposition of this category.For this, we find a condition involving supercuspidal support for two representations in R to have a non trivial extension space, and we use this to decompose the category R. At first, we work only with supercuspidal level 0 representations, then we deduce the general case

Texte intégralLet F be a local non archimedean field of characteristic not 2 and residual characteristic p. The local theta correspondence over F gives a bijection between some subsets of irreductible smooth complex reprensentations of a first reductive group H and a second reductive group H0, where (H,H0) is a dual pair in a symplectic group. Let R be a field of characteristic ℓ different from p. In this thesis, we give minimal conditions on R so thatStone-von Neumann’s theorem can be generalised in the setting of modular representation theory, which means when the coefficient field is R. This generalisation enables to define a modular Weil representation which verifies analogous properties to that of the complex case [MVW87]. When R is algebraically closed, we generalise the proof of the classical correspondence for non quaternionic dual pairs [GT16] under two assumptions. Firstly,the characteristic ℓ has to be greater than a certain explicit bound which depends on the pro-orders of H1 and H2. The second hypothesis have a deep connection to the theory of intertwining and would result from a better understanding of that theory in the modular setting
Ye, Shuyang. « On G-(phi,nabla)-modules over the Robba ring ». Doctoral thesis, Humboldt-Universität zu Berlin, 2019. http://dx.doi.org/10.18452/20359.
Texte intégralLet $K$ be a finite extension of $QQ_p$ and let $R$ be the Robba ring with coefficients in $K$, equipped with an absolute Frobenius lift $phi$. Let $F$ be the fixed field of $K$ under $phi$ and let $G$ be a connected reductive group over $F$. This thesis investigates $G$-$(phi,nabla)$-modules over $R$, namely $(phi,nabla)$-modules over $R$ with an additional $G$-structure. In Chapter 3, we construct a filtered fiber functor from the category of representations of $G$ on finite-dimensional $F$-vector spaces to the category of $QQ$-filtered modules over $R$, and prove that this functor is splittable. In Chapter 4, we prove a $G$-version of the $p$-adic local monodromy theorem. In Chapter 5, we prove a $G$-version of the logarithmic $p$-adic local monodromy theorem under certain assumptions. As an application, we attach to each $G$-$(phi,nabla)$-module a Weil-Deligne representation of the Weil group $W_{kk((t))}$ into $G(K^{nr})$, where $kk$ is the residue field of $K$, and $K^{nr}$ is the maximal unramified extension of $K$.

Texte intégralLet G be a p-adic group that splits over an unramified extension. We decompose Rep0 Λ(G), the abelian category of smooth level 0 representations of G with coefficients in Λ = Q` or Z`, into a product of subcategories. These categories are constructed via systems of idempotents on the Bruhat-Tits building and Deligne-Lusztig theory. A first decomposition is indexed by inertial Langlands parameters. We study the finest decomposition of Rep0 Λ(G) that can be obtained by this method. We give two descriptions of it, a first one on the group side à la Deligne-Lusztig, and a second one on the dual side à la Langlands. We prove several fundamental properties, like for example the compatibility to parabolic induction and restriction or the compatibility to the local Langlands correspondence. The factors of this decomposition are not blocks, but we show how to group them to obtain "stable" blocks. Some of these results support a conjecture given by Dat in [Dat17]. We also show that these categories are equivalent to categories obtained by systems of coefficient on the Bruhat-Tits building. Finally, we get `-blocks decompositions in some particular cases
Vu, Thi Minh Phuong. « Weak holonomicity for coadmissible equivariant D-modules on rigid analytic spaces ». Thesis, Rennes 1, 2020. http://www.theses.fr/2020REN1S040.
Texte intégralLet X be a smooth rigid analytic variety over a complete non-archimedian discrete valuation field K of mixed characteristic (0; p) and G be a p-adic group which acts continuously on X. The aim of this thesis is to develop a notion of weak holonomicity for coadmissible equivariant D-modules on X. In the following, we will give a summary for each chapter. After introducing the theory of D-modules on rigid analytic spaces and resuming the principal results of the thesis in the first chapter, we recall in the second chapter some basic notions and properties of rigid analytic geometry and of p-adic Lie groups, then we collect some important results of the theory of coadmissible G-equivariant D-modules on X which will be used in the next chapters. In the third chapter, we develop a dimension theory for coadmissible D(X;G)-modules. In order to do this, we first show that the K-algebra D(X;G) is coadmissibly Auslander-Gorenstein of dimension at most 2 dimX. This allows us to correctly define the dimension function on the category of coadmissible D(X;G)-modules. The fourth part of the thesis is devoted to the construction of so-called Ext-functors for all i and the study of weak holonomicity for coadmissible G-equivariant D-modules. The first part of this chapter we will working on many technical propositions in order to define, for each i , the functor E^i on the category C of coadmissible G-equivariant left D-modules. In the second part of Chapter 4, we define the notion of dimension of a coadmissible G-equivariant D-module and we prove that Bernstein's inequality holds for the case of rigid analytic flag varieties. This allows us to define weak holonomicity in this setting. We will also prove that there is a duality functor D on the category of coadmissible equivariant D-modules on X. In the last chapter we present some typical examples of weakly holonomic G-equivariant D-modules. Throughout we assume that Bernstein's inequality holds for the category C We prove that the extension of any equivariant integrable connection is weakly holonomic. In particular, we show that the structure sheaf O of X is a weakly holonomic G-equivariant D-modules. The second example comes from the case where X is the rigid analytic flag variety associated to a connected split algebraic group G over K. In this case, we show that Orlik-Strauch modules localize to G-equivariant D-modules which are weakly holonomic

Texte intégralThis thesis is concerned with the expansions of some algebraic structures and their fit in Shelah’s classification landscape. The first part deals with the expansion of a theory by a random –or generic– predicate for a substructure model of a reduct of the theory. We describe a setup allowing such an expansion to exist, which is suitable for several algebraic structures. In particular, we obtain the existence of additive generic subgroups of some theories of fields and multiplicative generic subgroups of algebraically closed fields in all characteristic. We also study the preservation of certain neostability notions, for instance, the NSOP 1 property is preserved but the simplicity is not in general. Thus, this construction produces new examples of NSOP 1 not simple theories, and we study in depth a particular example: the expansion of an algebraically closed field of positive characteristic by a generic additive subgroup. The second part studies expansions of the groups of integers by p-adic valuations. We prove quantifier elimination in a natural language and compute the dp-rank of these expansions: it equals the number of distinct p-adic valuations considered. Thus, the expansion of the integers by one p-adic valuation is a new dp-minimal expansion of the group of integers. Finally, we prove that the latter expansion does not admit intermediate structures: any definable set in the expansion is either definable in the group structure or is able to "reconstruct" the valuation using only the group operation
