Gozé, Vincent. "Une version effective du théorème des nombres premiers de Wen Chao Lu." Electronic Thesis or Diss., Littoral, 2024. http://www.theses.fr/2024DUNK0725.
Повний текст джерелаThe prime number theorem, first proved in 1896 using complex analysis, gives the main term for the asymptotic distribution of prime numbers. It was not until 1949 that the first so-called "elementary" proof was published: it rests strictly on real analysis.In 1999, Wen Chao Lu obtained by an elementary method an error term in the prime number theorem very close to the one provided by the zero-free region of the Riemann zeta function given by La Vallée Poussin at the end of the 19th century. In this thesis, we make Lu's result explicit in order, firstly, to give the best error term obtained by elementary methods so far, and secondly, to explore the limits of his method
Hanna, Gautier. "Blocs des chiffres des nombres premiers." Electronic Thesis or Diss., Université de Lorraine, 2016. http://www.theses.fr/2016LORR0162.
Повний текст джерелаThroughout this thesis, we are interested in asymptotic orthogonality (in the sense that the scale product of the discrete torus of length N tends to zero as N tend to infinity) between some functions related to the blocks of digits of integers and the Möbius function (and also the von Mangoldt function). Our work extends previous results of Mauduit and Rivat, and gives a partial answer to a question posed by Kalai in 2012. Chapter 1 provides estimates in the case of the function is the exponential of a function taking values on the blocks (with and without wildcards) of length k (k fixed) in the digital expansion of n in base q. We also give a large class of polynomials acting on the digital blocks that allow to get a prime number theorem and asymptotic orthogonality with the Möbius function. In Chapter 2, we get an asymptotic formula in the case of our function is the exponential of the function which counts blocks of consecutive ‘1’s in the expansion of n in base 2, where the length of the block is an increasing function that tends (slowly) to infinity. In the extremal case, which we cannot handle, this problem is connected to estimating the number of primes in the sequences of Mersenne numbers. In Chapter 3, we provides estimates on the case of the function is the exponential of a function which count the blocks of k ‘1’s in the expansion of n in base 2 where k is large with respect to log N. A consequence of Chapter 3 is that the results of Chapter 1 are quasi-optimal

Повний текст джерелаIn the first part of this Thesis, we study the sequence NX (p) [mod p] where X is a reduced separated scheme of finite type over Z,and NX (p) is the number of Fp-points of the reduction modulo p of X, for every prime p. Under some hypotheses on the geometry of X, we give a simple condition to ensure that this sequence is distinctat a positive proportion of indices from the zero sequence,or generalizations obtained by reduction modulo p of finitely many integers.We give a bound on average over a family of hyperelliptic curves for the least prime p such that NX (p) [mod p] avoids the reductionmodulo p of finitely many fixed integers.The second part deals with generalizations of Chebyshev’s bias.We consider an L-function satisfying some analytic properties that generalize those satisfied by Dirichlet L-functions.We study the sequence of coefficients a_p as p runs through the set of prime numbers.Precisely, we study the sign of the summatory function of the Fourier coefficients of the L-function.Under some classical conditions, we show that this function admits a limiting logarithmic distribution.Under stronger hypotheses, we prove regularity, symmetry and get information about the support of this distribution
Plet, Sébastien. "Mesures et densités des nombres premiers dans les suites récurrentes linéaires." Caen, 2006. http://www.theses.fr/2006CAEN2069.
Повний текст джерелаWe give a general construction of probability measures on [0, 1] linked with representations of real numbers in a variable basis and with some so-called density function. This general constructions is shown to naturally associate a probability space to a profinite group and, in particular, to define a probability measure on the Galois group of an infinite Galois extension of a number field. Our probabilistic formalism is then applied on two distinct problems. First, we solve conjectures of Paul Bruckman and Peter Anderson on the rank of an integer in the Fibonacci sequence. Secondly, we compute the density of maximal prime divisors for an infinite family of third order integral linear recurring sequences

Повний текст джерелаThis thesis is about lower bounds for the biggest prime divisors of linear recurrent sequences. First, we obtain a uniform and explicit version of Stewart’s seminal result about prime divisors of Lucas sequences. We show that constants in Stewart’s theorem depend only on the quadratic field corresponding to a Lucas sequence. Then we study the prime divisors of orders of elliptic curves over finite fields. Fixing an elliptic curve over Fq with q power of a prime number, the sequence #E(Fqn) happens to be a linear recurrent sequence of order 4. Let P(x) be the biggest prime dividing x. A lower bound of P(#E(Fqn)) is given by using Stewart’s argument and some more delicate discussions. Next, motivated by our previous two projects, we can show that when γ is an algebraic number of degree 2 and not a root of unity, there exists a prime ideal p of Q(γ) satisfying νp(γn − 1) ≥ 1, such that the rational prime p underlying p grows quicker than n. Finally, we consider a numerical application of Stewart’s method to Fibonacci numbers Fn. Relatively sharp bounds for P(Fn) are obtained. All of the above work relies heavily on Yu’s estimate for p-adic logarithmic forms

Повний текст джерелаIn this thesis, we study the largest prime factors of consecutive integers. Denote by P^+(n) (resp. P^-(n)) the largest (resp. the smallest) prime factors of the integer n\geq 1 with the convention P^+(1)=1 (resp. P^-(1)=\∞). In the first chapter, we consider the largest prime factors of consecutive integers in short intervals. We prove that there exists a positive proportion of integers n for n\in\, (x,\, x+y] with y=x^{\theta}, \tfrac{7}{12}<\theta\leq 1 such that P^+(n)P^+(n+1). In the second chapter, we consider the function P_y^+(n), where P_y^+(n)=\max\{p|n:\, p\leq y\} and 2\leq y\leq x. We prove that there exists a positive proportion of integers n such that P_y^+(n)P^+(n)P^+(n+1) occur for a positive proportion of integers n respectively, by the well adapted system of weights that we have developed in the second chapter. With the same method, we derive a more general result for k consecutive integers, k\in \mathbb{Z}, k\geq 3. In the fourth chapter, we study the largest prime factors of consecutive integers with one of which without small prime factor. Firstly we show that under the Elliott-Halberstam conjecture, the proportion of the pattern P^+(p-1)x^{\beta} with 0<\beta<\frac{1}{3}
Goudout, Elie. "Étude de la fonction ω : petits intervalles et systèmes translatés". Thesis, Sorbonne Paris Cité, 2019. http://www.theses.fr/2019USPCC040.
Повний текст джерелаIn this thesis, we study the interactions between the multiplicative and additive structures of integers. As such, we particularly investigate the function “number of distinct prime factors”, noted ω, on short intervals and shifted systems. This project originates from an important breakthrough of Matomäki & Radziwiłł regarding the study of small intervals, in 2015. As a first step, we show that the Erdős-Kac theorem is valid in almost all short intervals, as long as their length goes to infinity. We then consider the local laws of ω. We prove that, for x> 3 and , almost all intervals of length h contain integers n 6 x satisfying ω(n) = k, when h is large enough. For , the condition on h is optimal. A similar result, albeit non optimal, is obtained for x1/u-friable integers with u 6 (logx)1/6−ε, where ε > 0 is fixed, arbitrarily small. The techniques used in the second chapter naturally invite us to consider the behavior of a wide class of additive functions on shifted systems. In the third chapter, we prove a multidimensional version of a theorem from Halász in 1975, regarding the maximum concentration of the values of one additive function. In the last chapter, we show that ω(n− 1) satisfies an Erdős-Kac theorem whenever ω(n) = k is fixed. This generalizes a theorem of Halberstam
Milovic, Djordjo. "On the 16-rank of class groups of quadratic number fields." Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLS157/document.
Повний текст джерелаWe prove two new density results about 16-ranks of class groups of quadratic number fields. The first of the two is that the class group of Q(sqrt{-p}) has an element of order 16 for one-fourth of prime numbers p that are of the form a^2+c^4 with c even. The second is that the class group of Q(sqrt{-2p}) has an element of order 16 for one-eighth of prime numbers p=-1 (mod 4). These density results are interesting for several reasons. First, they are the first non-trivial density results about the 16-rank of class groups in a family of quadratic number fields. Second, they prove an instance of the Cohen-Lenstra conjectures. Third, both of their proofs involve new applications of powerful sieving techniques developed by Friedlander and Iwaniec. Fourth, we give an explicit description of the 8-Hilbert class field of Q(sqrt{-p}) whenever p is a prime number of the form a^2+c^4 with c even; the lack of such an explicit description for the 8-Hilbert class field of Q(sqrt{d}) is the main obstacle to improving the estimates for the density of positive discriminants d for which the negative Pell equation x^2-dy^2=-1 is solvable. In case of the second result, we give an explicit description of an element of order 4 in the class group of Q(sqrt{-2p}) and we compute its Artin symbol in the 4-Hilbert class field of Q(sqrt{-2p}), thereby generalizing a result of Leonard and Williams. Finally, we prove a power-saving error term for a prime-counting function related to the 16-rank of the class group of Q(sqrt{-2p}), thereby giving strong evidence against a conjecture of Cohn and Lagarias that the 16-rank is governed by a Chebotarev-type criterion

Повний текст джерелаInformation is very precious, this is the reason why it must be protected both in databasis and during transmission. Integer factoring is a diffcult problem and a cornerstone for safety in asymmetric cryptography. Thus it is very important to be able to check for the primality of big integers for asymetric cryptography. To do this we use primality tests. The AKS test is a deterministic polynomial time primality proving algorithm proposed by Agrawal, Kayal and Saxena in August 2002 ('Primes is in P'). The Elliptic Curves Primality Proving (ECPP), proposed by A. O. L. Atkin in 1988, is a probabilistic test. It is one of the most powerful primality tests that is used in practice. The purpose of this thesis is to give an elliptic version of the AKS primality criterion involving a ring of elliptic periods. Such a ring is obtained as a residue ring at a torsion section on an elliptic curve defined on Z/nZ. This section plays the role of the root of unity in the original AKS test. We give a general criterion in terms of etale extensions of Z/nZ equipped with an automorphism, and we show how to build such extensions using isogenies between elliptic curves modulo n

Повний текст джерелаThis thesis develops both theoretical and numerical aspects of the explicit theory of prime numbers, mainly from the real analysis viewpoint. Its general framework was initiated by Michel Balazard who obtained integral identities relating the summatory function M of the Möbius coefficients with its logarithmic variant m. We present a systematic mechanism towards such identities, with an integrable function g on [0,1] as parameter. We focus particularly on polynomial g's (as they provide all identities previously published by Balazard), and aim at optimizing some sup norm for the use of the associated identities of integrals. We detail the strategy of numerical explorations, whose ultimate objective is the study of some constants tacitly defined byBalazard. Then we turn to obtaining exact values for sup{|m(x)-M(x)/x| (\log x)^j : x>T } for j=0,1,2 and some T's. Next, we obtain an effective lower bound of an average of |M|, related to a result of Pintz, but with a fundamentally distinct approach using almost no complex analysis. And we then give the analogous result for the summatory function of the Liouville coefficients. Also, we consider the best known non-effective estimates for M(x) and show how to transform them into estimates of xm(x) - M(x) of the same type. The techniques and obtained results dealing with m and M are partially extended to other arithmetical functions

Повний текст джерелаE.Bombieri and J.Pila introduced a method to bound the number of integral points in a small given box (under some conditions). In algebraic part we generalise this method to the case of function fields of genus $0$ in ove variable. Then we apply the result to count the number of elliptic curves falling in the same isomorphic class with coefficients lying in a small box.Once we are done the natural question is how to improve this bound for some particular families of curves. We study the case of elliptic curves and use the fact that the necessary part of Birch Swinnerton-Dyer conjecture holds over function fields. We also use the properties of height functions and results about sphere packing.In analytic part we give an explicit version of Bombieri-Vinogradov theorem. This theorem is an important result that concerns the error term in Dirichlet's theorem in arithmetic progressions averaged over moduli $q$ up to $Q$. We improve the existent result of such type given in cite{Akbary2015}. We reduce the logarithmic power by using the large sieve inequality and Vaughan identity

Повний текст джерелаIn this thesis we are interested in a generalization of the notion of primitive root proposed by Carmichael: an integer a is a generalized primitive root modulo a positive integer n if it generates a subgroup of maximal size in “mathbb{Z}/nmathbb{Z}”. More precisely, we study an analogue of Artin's conjecture for primitive roots in this framework. Artin's conjecture states that the proportion of primes smaller than x, for which a given integer a is a primitive root, converges to a nonzero limit as long as a is neither -1 nor a square. This conjecture was proved conditionally on the generalized Riemann hypothesis for certain numbers fields by Hooley in 1967.By analogy with Artin's conjecture we count the number of elements of a subset of positive integers A smaller than x for which a given integer a is a generalized primitive root. The case where the set A is the set of all positive integers has already been treated by Li and Pomerance in various papers. In the first chapter of this thesis we introduce a characterization of generalized primitive roots modulo an integer n in terms of the prime factorization of n, and then we describe a heuristic approach to the problem. The second chapter is devoted to the case where the set A is the set of ell almost primes, i.e. the integers having at most ell prime factors. Using sieve methods, results from algebraic number theory, the Selberg-Delange method and some combinatorial arguments we prove, conditionally on the generalized Riemann hypothesis, results similar to those obtained by Hooley for the Artin conjecture. Moreover, we show unconditionally an upper bound for the proportion of almost primes for which a is a generalized primitive root. Finally, we show that in the special case where ell=2, a better error term can be obtained by replacing the Selberg-Delange method by the hyperbola method. In the third and last chapter we consider the case where A is the set of sifted “x^heta” integers, i.e. the integers having no prime factor smaller than “x^heta”, for 0

Le thème unificateur de notre thèse est la détection de structures additives dans les ensembles arithmétiques à faible densité, avec un intérêt particulier pour les aspects quantitatifs. Notre première contribution est une estimation de densité améliorée pour le problème, initié entre autres par Bourgain, de trouver une longue progression arithmétique dans un ensemble somme triple. Notre deuxième résultat consiste en une généralisation des bornes de Sanders pour le théorème de Roth, du cas d'un ensemble dense dans les entiers à celui d'un ensemble à faible croissance additive dans un groupe abélien arbitraire. Finalement, nous étendons les meilleures bornes quantitatives connues pour le théorème de Roth dans les premiers, à tous les systèmes d'équations linéaires invariants par translation et de complexité un.
We present three results in additive combinatorics, a recent field at the interface of combinatorics, harmonic analysis and analytic number theory. The unifying theme in our thesis is the detection of additive structure in arithmetic sets of low density, with an emphasis on quantitative aspects. Our first contribution is an improved density estimate for the problem, initiated by Bourgain and others, of finding a long arithmetic progression in a triple sumset. Our second result is a generalization of Sanders' bounds for Roth's theorem from the dense setting, to the setting of small doubling in an arbitrary abelian group. Finally, we extend the best known quantitative results for Roth's theorem in the primes, to all translation-invariant systems of equations of complexity one.

Повний текст джерелаIn this thesis, we are interested in multiple aspects of the theory of prime number races, initiated by Rubinstein and Sarnak in 1994. In the first chapter, we explain Rubinstein and Sarnak's method, we give an overview of extensions of their work, and we develop their method in a general setting, with the goal of weakening as much as possible their working hypothesis about the linear independence of the imaginary parts of non-trivial zeros of Dirichlet L-functions. In the second chapter, we are interested in the generalisation of problems of prime number races in the context of the distribution of Frobenius automorphisms in Galois groups of number field extensions. Following recent work of Fiorilli and Jouve, we highlight the influence that the vanishing at 1/2 of some Artin L-functions can have on such races. In the third and final chapter, we are interested in the same kind of questions as before in the context of extensions of function fields in one variable over finite fields, and we prove a new central limit theorem for superelliptic extensions

Повний текст джерелаIn this work, we study the distribution of prime numbers' digits. Bourgain (2015) obtained an asymptotic formula for the number of prime numbers with a proportion $c > 0$ of preassigned digits in base 2 ($c$ is an absolute constant not specified). We generalize this result in any base $g \geq 2$ and we provide explicit admissible values for the proportion $c$ depending on $g$.By adapting, developing and refining Bourgain's strategy in the case $g=2$, we present a detailed proof for the general case.The proof is based onthe circle method and combines techniques from harmonic analysis together with results onzeros of Dirichlet $L$-functions, notably a very sharp zero-free region due to Iwaniec.This work also falls within the study of prime numbers in sparse ``sets''.In addition, we study the distribution of the ``digits'' (in the sense of Dartyge and S\'ark\"ozy) of some sequences of interest in the context of finite fields. This concept of ``digits'' is fundamental in the representation of finite fields in computer algebra systems. We study various sequences such as polynomial sequences, generators as well as products of elements of two large enough sets.Our methods provide very sharp explicit estimates which are even optimal in some cases.Exponential sums over finite fields play an essential role in the proofs.Our results can be reformulated from a more algebraic point of view with the trace function which is of basic importance in the study of finite fields

Повний текст джерелаWe improve Bombieri’s asymptotic sieve to localise the variables. As a consequence, we prove, under a Elliott-Halberstam conjecture, that there exists an infinity of twins almost prime. Those are prime numbers p such that for all ε > 0, p −2 is either a prime number or can be written as p1p2 where p1 and p2 are prime and p1 < Xε, and we give the explicit asymptotic. In addition to this main work, there are two other chapters: the first one gives an asymptotic of prime numbers p such p−2is either a prime number or a product of three primes without using a preliminary sieve and so a stronger conjecture was needed. Hence this part shows the strength of the preliminary sieve and presents a few detailed sommations, most of them involving the Möbius fonction, that could be useful. The second one presents an easy and explicit method to calculate an average order of multiplicative functions

Повний текст джерелаNumbers with missing digits and palindromic numbers (with respect to a fixed basis) are subset of the integers. This subsets are defined by digital conditions and are scattered. We study if this sets have multiplicative properties similar to those of the integers. Firstly, we evaluate the high moments of the generating series of numbers with missing digits. As a application, we show that there is a 0 < c < 1 such that for all integer k, the integers n with missing digits which have a factor p^k with p^k~n^c and p a prime, are innumerable. Moreover the number of such integers has the expected size. Secondly, we establish a result of sieve where the modules with an abnormally large number of divisors are expelled of the error term. We deduce consequently the existence of a positive proportion of numbers with missing digits which have no large prime factors. Thirdly, using elementary methods, we show how to reduce the study of the generating series of the palindromes to a series close to that of the numbers with missing digits. This makes possible to study their repartition in the arithmetical progressions and thus to obtain an upper bound for the palindromic primes. We deduce in particular that the palindromes with at most 372 prime factors in basis 10 are endless

Повний текст джерелаThis thesis concerns a few problems linked with the distribution of squarefree integers in arithmeticprogressions. Such problems are usually phrased in terms of upper bounds for the error term relatedto this distribution.The first, second and fourth chapter focus on the satistical study of the error terms as the progres-sions varies modulo q. In particular we obtain an asymptotic formula for the variance and non-trivialupper bounds for the higher moments. We make use of many technics from analytic number theorysuch as sieve methods and exponential sums. In particular, in the second chapter we make use of arecent upper bound for short exponential sums by Bourgain.In the third chapter we give estimates for the error term for a fixed arithmetic progression. Weimprove on a result of Hooley from 1975 in two different directions. Here we use recent upper boundsfor short exponential sums by Bourgain-Garaev and exponential sums twisted by the Möbius functionby Bourgain et Fouvry-Kowalski-Michel

Повний текст джерелаIn this thesis, we deal with two problems : sign changes of Kloosterman's sums Kl(1,1;n) for n with few prime factors, and small gaps between non-consecutive primes. In the first chapter, we improve on a result of Fouvry-Michel by iterating once the strange sieve they have introduced, in order to get a lower bound. This allows us to prove that Kl(1,1;n) changes sign infinitely often on the set of all n whose prime factors are greater that n^(1/22. 29) (instead of 23. 9). In the second chapter, we introduce Sato-Tate's vertical law into the asymptotic sieve. This implies new problems to deal with error terms ; we solve them using Barban-Davenport-Halberstam's theorem. We prove the following result : Kl(1,1;n) changes sign infinitely often on the set of all square-free n with at most 18 prime factors (instead of 23 for Fouvry-Michel). In this aim, we compute (thanks to the residue theorem) 5-fold integrals of rational fractions in Riemann zeta function. This computation is worked out in a very general setting through a technical lemma, to which Chapter 3 is devoted. The fourth chapter deals with such integrals, too, but which don't fit into that setting. These integrals appear in Goldston-Yildirim's works on multiple correlations of the truncated Von Mangoldt function. By combining this approach with Maier's, we improve on the best known upper bound (due to Maier) of liminf (p_(n+r)-p_n)/(log p_n) for r ≥2 (where p_n stands for the n-th prime number)

Повний текст джерелаLet K be an imaginary quadratic field in which the rational prime p splits in two factors, say p and p̄. To the pair (K,p), Katz and Yager were able to associate a p-adic L function with two variables. Coates and Greenberg formulated the so-called main conjecture asserting the equality of this p-adic L fuction with the characteristic power series of the unramified outside p Iwasawa module. In this thesis, we prove (for "half" of the diedral charcters) that this conjecture, specialised to the antyciclotomic variable is true. Our proof is rather heavy because of its extensive use of the theory of congruence module of Δ-adic ordinary forms built by H. Hida. However, it may be well suited for the generalisations to CM-fields

Повний текст джерелаLa seconde partie de cette thèse se place dans le contexte de la théorie additive des nombres. Nous développons une nouvelle approche de la méthode isopérimétrique de Y. ould Hamidoune, qui nous permet, entre autres, de donner une nouvelle démonstration du théorème de Kneser, outil majeur en théorie additive des nombres. Nous donnons une autre application de cette nouvelle approche à la détermination de nouvelles valeurs de taille minimale d'une somme de deux ensembles de tailles fixées, dans des groupes non abéliens. Ces nouvelles valeurs répondent par la négative à une question de la littérature.

Повний текст джерелаIn this Thesis we give applications of two important ideas in Set Theory. One of these ideas is the reflection of stationary sets. The second idea is that strengthening the logic in Gödel's compactness theorem gives rise to a variety of interesting large-cardinal axioms and other compactness principles with influence to so basic questions of modem Set Theory such as, for example, the problem about the cardinality of the continuum and other questions about the cardinal arithmetic. We show that the Weak Reflecting Principle (WRP) together with the saturation of the ideal NS imply that for every regular cardinal thêta grater than aleph 1, thetaA(omega_l)=theta. As indicated above, another theme of this Thesis is the compactness of infmitary logics. We prove that Rado's conjecture together with the saturation of the ideal NS imply Diamond_{[omega_n]A{omega_l}} for every natural number n grater than 1. In fact, the diamond sequences that we get concentrate on sets that have uniformly uncountable cofinality omega_l. We expect that further work will lead us to similar consequences to ail other regular cardinal numbers greater than or equal to omega_2

Повний текст джерелаWithout rejecting the influence of culture and the necessity of intuition, this Doctorate claims its mathematical approach. The start hypothesis is that major and minor triads are : {°C & °G & °E} = {°1 & °3 & °5} and {°C & °G & ° E = {°1 & °3 & °19}. This writing depends explicitly on the analysis as combinations of prime factors of the numbers of the frequency ratios, and incorporate concepts of octave identity and inversion. The “ Basse fondamentale ” concept of Rameau is identified to “ son 1 ”, in parallel with concepts of numerical tonic, “ °1 ”, and time tonic, “ °T ”. With this “ numerical-functional ” approach, and on the basis of chord links hypothesis (which goes beyond the principle of “ common tones ”, for instance “ °3 Þ °1 ”, “ dominant ” becomes “ tonic ”, for I-V), the coherence of several verbal concepts is studied and confronted with “ °19 hypothesis ” : the cadence with two leading notes, “ great sixth ” chord, degree iii in major. Third part studies more specifically progressions, considering commas which are characteristic of some of them clearly as a “ partial factor ” (with the Dahlhaus meaning of these terms) and not as anomalies. Fourth part confronts some verbal analysis of part of scores with “ numerical-functional ” analysis. Some sounding examples were built note by note with one cent precision in order to give the reader the possibility of verifying if he can effectively “ hear as ”, or “ understand as ” it is mathematically proposed

Повний текст джерелаÀ travers ce travail, nous nous intéressons au cas des corps de nombres de degré n ≤ 9. Après quelques rappels généraux sur les outils utilisés, on présente les méthodes pratiques permettant de vérifier cette conjecture.
Les travaux de J. Jones ont montré que les corps de nombres de degré 5 et 6 vérifiant ces types de ramification ont tous un groupe de Galois résoluble.
Dans le cas du degré 7, S. Brueggeman a abouti au même résultat que le travail sus cité.
Nos travaux dans le cas des degrés 8 et 9 montrent que sous GRH ou de façon inconditionnelle, la ramification en 5 n'est pas possible. À l'issue des recherches numériques, les seules tables obtenues sont celles de la ramification en p = 2 en degré 8 et celles de la ramification en p = 3 en degré 9. Les corps obtenus ont tous un groupe de Galois résoluble, montrant ainsi que cette conjecture de B. Gross n'est pas vérifiée pour les corps de nombres de degré n ≤ 9.

Повний текст джерелаNous évaluons d'abord les grands moments de la série génératrice des entiers ellipséphiques. Comme application, nous en déduisons l'existence d'un 0 < c < 1 tel que pour tout entier k, une infinité d'entiers ellipséphiques n possédant un diviseur p^k de l'ordre de n^c, p désignant un nombre premier. De plus, le nombre de tels entiers est de l'ordre de grandeur attendu.
Nous établissons ensuite un résultat de crible où les modules possédant un nombre anormalement grand de diviseurs sont écartés du terme d'erreur. Nous en déduisons l'existence d'une proportion positive d'entiers ellipséphiques friables c'est-à-dire possédant tous leurs facteurs premiers majorés par n^c, pour une constante c < 1 fixée.
Nous montrons enfin à l'aide de techniques élémentaires comment réduire l'étude de la série génératrice des palindromes à une série proche de celle des entiers ellipséphiques ce qui permet d'étudier la répartition des palindromes dans les progressions arithmétiques et ainsi d'obtenir une majoration de l'ordre de grandeur attendu du nombre de palindromes premiers. Nous en déduisons en particulier l'existence d'une infinité de palindromes possédant en base 10 au plus 372 facteurs premiers (comptés avec multiplicité).
