Full textOhta has given a detailed study of the ordinary part of p-adic Eichler-Shimura cohomology groups (resp., generalized p-adic Eichler-Shimura cohomology groups) from the perspective of p-adic Hodge theory. Assuming various hypotheses, he is able to use the structure of these groups to give a simple proof of the Iwasawa main conjecture over Q. The goal of this thesis is to extend Ohta’s arguments with a view towards removing these hypotheses.

Full textA 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

Full textLet F be a number field unramified at an odd rational prime p. Let F∞ be the Zp-cyclotomic extension of F and Λ = Zp[[Gal(F∞/F)]] be the Iwasawa algebra of Gal (F∞/F) (signe de asymptotiquement égal) Zp over Zp. Generalizing Kobayashi’s plus and minus Selmer groups, Büyükboduk and Lei have defined signed Selmer groups over F∞ for some non-ordinary Galois representations. In particular, their construction applies to abelian varieties defined over F with good supersingular reduction at primes of F dividing p. These signed Selmer groups have a natural structure of finitely generated Λ-modules. We first prove a functional equation for these signed Selmer groups, relating the signed Selmer groups of such a representation to the signed Selmer groups of Tate dual of the representation. Second, we study the structure of Λ-module of the signed Selmer groups. Assuming that they are cotorsion Λ-modules, we show that they have no proper sub-Λ-module of finite index. We deduce from this a number of arithmetic applications. We compute the Λ-corank of the Bloch-Kato Selmer group attached to the representation over F∞, and, on studying the Euler-Poincaré characteristic of these signed Selmer groups, we obtain an explicit formula on the size of the Bloch-Kato Selmer group over F. Furthermore, for two such representations that are isomorphic modulo p, we compare the Iwasawa-invariants of their signed Selmer groups. Finally, under the hypothesis that the signed Selmer groups associated to a supersingular abelian variety are cotorsion Λ-modules, we show that the rank of Mordell-Weil groups of the abelian variety is bounded along the cyclotomic extension.

Full textThis work is concerned with the study of logarithmic invariants on $l^{d}$-extensions and is subdivided in three pieces, which are closely related to each other. The first part is a compendium of the different approaches to logarithmic arithmetic, that is the study of the logarithmic invariants. In particular we show the equivalence between the four definitions of the logarithmic class group existing in the literature. Also we give an alternative proof of an Iwasawa logarithmic result. The second part can be thought as an historic addendum on the study of the logarithmic class group over $l$-extensions. Assuming the Gross-Kuz'min conjecture we show that the logarithmic class group can be studied in the Iwasawa setting for non-cyclotomic extensions. We also give relations between the classical $mu$ and $lambda$ invariants and the logarithmic invariants $ilde{mu}$ and $ilde{lambda}$ attached to the logarithmic class groups. The third part studies the properties of the Iwasawa logarithmic module for $l^{d}$-extensions, that is the Galois group $X=Gal(L_{d}/K_{d})$ of the maximal abelian $ell$-extension logarithmically unramified of the compositum $K_{d}$ of the different $l$-extensions of a number field $K$. Assuming the Gross-Kuz'min conjecture we show that $X$ is a noetherian torsion module over the Iwasawa algebra of $K_{d}$. We also deduce relations between the logarithmic invariants $ilde{mu}$ and $ilde{lambda}$ of the $l$-extensions of $K$ which satisfy a splitting condition

Full textThis thesis aim at exploring Iwasawa invariants attached to generalized p-class groups in p-adic Lie extensions of number fields. These invariants where introduced by Iwasawa for Zp-extensions. In his work on the structure of modules over the Iwasawa algebra of a p-adic Lie group, Venjakob extends the definition to the non commutative theory. Using descent techniques, along with a fine algebraic study of Iwasawa's modules structure over a non commutative group, we obtain asymptotic formulas for generalized p-class groups in a tower of number fields, with a p-valued group as Galois group. These formulas have Iwasawa invariants as parameters. They become more precise for Zp-extensions, where a significant descent default is involved. These asymptotic results are exploited thanks to reflexion theory. This leads to duality formulas between ramification and decomposition for Iwasawa invariants

Full textIn the first chapter of this thesis we explain Leopoldt's conjecture and some equivalent formulations. Then we give an algorithm that checks this conjecture for a given prime p and a number field. Next we assume that this conjecture is true, and we study the torsion part of the Galois group of the maximal abelian p-ramified p-extension of a given number field. We present a method to compute the invariant factors of this finite group. In the third chapter we give an interpretation of our numrical result by heuristics “à la” Cohen-Lenstra. In the fourth and last chapter, using our algorithm which computes this torsion submodule, we give new examples of numbers fields which satisfy Greenberg's conjecture

Full textLet 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.

Full textThe aim of the present work is to prove some results about étale wild kernels. Let $p$ be an odd prime. Etale wild kernels of a number field $F$ (which are denoted $WK^{ét}_{2i}(F)$ for $i\in \mathbb{Z}$) are cohomological generalizations of the $p$-part of the classical wild kernel $WK_{2}(F)$, which is the subgroup of $K_2(F)$ made up by symbols which are trivial for any local Hilbert symbol. Etale wild kernels are $\mathbb{Z}_p$-modules which are known to be finite if $i\geq1$ (and even if $i=0$, depending on the chosen convention): actually they are conjectured to be always finite (the Schneider conjecture). In the following we will suppose that this is always the case. Two problems are studied in detail. The first, which is analyzed in Chapter 2 and Chapter 3, is to determine which group structures are realizable for étale wild kernels. In other words, given a number field $F$, a finite abelian $p$-group $X$ and $i\in \mathbb{Z}$, one can ask if there exists a finite extension $E/F$ such that $WK^{ét}_{2i}(E)\cong X$. A similar problem has been studied for $p$-class groups and there are precise relations between the $p$-class group and étale wild kernels. Therefore one may expect to translate results from $p$-class groups to étale wild kernels. It is maybe useful to give here a short account on the classical realizability problem for $p$-class groups. Essentially two kind of techniques are used. On the one hand, for a fixed number field $F$, one studies the Hilbert $p$-class field tower of $F$: it has been shown by Yahagi that the Hilbert $p$-class tower of $F$ is infinite if and only if there is no finite extension $E/F$ whose $p$-class group is trivial. Furthermore, if the Hilbert $p$-class tower of $F$ is finite, then every finite abelian $p$-group structure appears as $p$-class group of some finite extension $E/F$. On the other hand, once we know that for a fixed number field $F$ there exists a finite extension whose $p$-class group is trivial, then class field theory and genus theory are used to exhibit, for any finite abelian $p$-group $X$, a finite extension $E/F$ such that the $p$-class group of $E$ is isomorphic to $X$. Actually, the translation of Yahagi's result in terms of étale wild kernels is not immediate: the relation between the class groups and étale wild kernels of a number field $F$ is expressed in terms of $\Gamma$-modules structures, where $\Gamma$ is the Galois group over $F$ of the cyclotomic $\mathbb{Z}_p$-extension of $F(\mu_p)$. The most natural way to approach the problem is then to consider the realizability problem for Iwasawa modules. This problem is studied (among many others) by Ozaki: he proved that for any finite $\Lambda$-module $X$, there exists a number field $k$ such that the Iwasawa module of $k$ (i.e. the projective limit of $p$-class groups along the cyclotomic $\mathbb{Z}_p$-extension) is isomorphic to $X$. The techniques used are inspired to those by Yahagi and actually Ozaki makes fundamental use of the fact that $p$ does not divide the class number of $\mathbb{Q}$. To get the translation of this result in terms of étale wild kernels one has to consider $\mathbb{Q}(\mu_p)$ -more precisely a suitable subfield of $\mathbb{Q}(\mu_p)$ depending on $i$- instead of $\mathbb{Q}$. Here the problem is that the class number of this suitable subfield is no more coprime with $p$ (as $p$ may be irregular). If this is not the case anyway, the proof of Ozaki can be adapted as it is shown in Chapter 2

Full textLet p be a prime number, let K/k be a Galois extension of number fields and let S be a finite set of primes of K. We suppose that the degree of K/k is finite and coprime to p. We denote by G(K,S) the Galois group of the pro-p maximal extension of K unramified outside S. We focus on this thesis on two differents aspects of this pro-p group.We are first interested in the tame case : we suppose that S does not contain any place above p. The works of Labute, Minac and Schmidt about mild pro-p groups brought the first examples of groups G(K,S) of cohomological dimension two. Using a corollary of their criterium, we compute some examples with PARI/GP and we observe a propagation phenomenum : if we take K=Q and if we suppose that G(Q,S) is mild, a large part of the pro-p groups G(K,S) with K imaginary quadratic are mild too. We then associate two oriented graphs to G(K,S) and we show a theoretical criterium proving mildness of some imaginary quadratic fields.We then consider the wild case where all the places dividing p belong to S. The Galois group Δ:=Gal(K/k) acts on G(K,S). The action of Δ is trivial on some quotients of G(K,S) ; we denote by G the maximal one and by H the corresponding closed subgroup of G(K,S). Maire has studied the Zp[[G]]-freeness of the module H^{ab}. We extend his results considering the φ-component of H^{ab} under the action of Δ. In a favourable context and under Leopoldt's conjecture, we show a necessary and sufficient condition for the freeness of the φ-components. This condition is connected to p-rational fields by class field theory. We present experiments with PARI/GP in some families of cubic cyclic, dihedral and quartic cyclic extensions of Q which support the following conjecture from Gras : every number field is p-rational for sufficiently large p

Full textIn this thesis, we construct Euler systems coming from the (conjectural) Stark units and those of Rubin-Stark of a number field K, to describe the characteristic ideal of the X-quotient of the standard Iwasawa module X∞, for some p-adic irreducible characters X. Here X∞ is the Galois group of the maximal unramified abelian pro-p-extension of K∞, where K∞ is an adequate Zp-extension of K. Precisely, we demonstrate a divisibility results formulated by the main conjecture of Iwasawa theory. Our demonstrations essentially are based on the theory of Euler systems

Full textThis thesis studies the construction of p-adic L-functions associated to motives over Q and, in particular, to modular forms.In the first three chapters we generalize some constructions of Perrin-Riou in order to construct, for any p-adic de Rham representation V of the absolute Galois group G_Qp of Qp (or, more generally, any de Rham (ϕ,Γ)-module over the Robba ring) and any compatible system of global elements, a p-adic L-function. We show, by the use of some reciprocity laws proved by Perrin-Riou, Colmez, Cherbonnier-Colmez, Berger and Nakamura, that these functions interpolate interesting arithmetic values at locally algebraic characters.The last three chapters deal with the particular case of dimension 2. We show, inspired by some techniques of Nakamura and certain weight change techniques introduced by Colmez for the study of locally algebraic vectors in the p-adic Langlads correspondence for GL₂(Qp), that our p-adic L-function satisfies a functional equation. As an application of our functional equation, we fulfil the missing arguments in the work of Nakamura, providing a complete proof of Kato's local ε-conjecture for 2-dimensional representations. For the motive associated to a modular form, we use these results to interpret the interpolated values of the p-adic L-function in terms of special values of the complex L-function of the form

Full textThe goal of this work is to show how Euler systems allows us to compare, for some abelian extensions, the Galois module of global units modulo Stark units with the Galois module of ideal p-classes. We restricts ourselves to abelian extensions over a base field k which can be an imaginary quadratic field or a global field of positive characteristic. The Gras conjecture predicts that for all finite abelian extension K/k, all prime number p not dividing [K : k], and all irreducible and nontrivial Qp-character ψ of Gal (K/k), the ψ-part of the p-class group of K and the ψ-part of the group of global units modulo Stark units have the same cardinal. First we prove a weak form of the conjecture, and then we use Euler systems to extend the results obtained among others by Rubin, Xu et Zhao. Then we assume that k is an imaginary quadratic field, and we consider a special Zp-extension k∞ of k, where p is a prime number different from 2 and 3, decomposed in k. We prove that for all finite extension K∞ of k∞ abelian over k, and for all irreducible Cp-character χ of the torsion subgroup of Gal(K∞/k), the characteristic ideal of the χ-quotients of the module of p-classes and the characteristic ideal of the module of global units modulo Stark units are the same. It is one of the versions of the main conjecture in Iwasawa theory, which extends a result of Rubin and Bley. It is also a step for a further work, where we extend a result of Rubin on the two variables main conjecture
