R´esum´e. Une construction hyperg´eom´etrique g´en´erale de formes lin´eaires de valeurs de la fonction z´eta aux entiers impairs est pr´esent´ee. Cette construction permet de retrouver les records de Rhin et Violla pour les mesures d’irrationnalit´e de ζ(2) etζ(3), ainsi que d’expliquer les r´esultats r´ecents de Rivoal sur l’infinit´e des valeurs irrationnelles de la fonction z´eta aux entiers impairs et de prouver qu’au moins un des quatre nombresζ(5),ζ(7),ζ(9) etζ(11) est irrationnel.

Abstract. A general hypergeometric construction of linear forms in (odd) zeta values is presented. The construction allows to recover the records of Rhin and Viola for the irrationality mea-sures ofζ(2) andζ(3), as well as to explain Rivoal’s recent result on infiniteness of irrational numbers in the set of odd zeta values, and to prove that at least one of the four numbersζ(5),ζ(7),ζ(9), andζ(11) is irrational.

We will use fairly classical techniques in Section 2 below to show that, as far as the behavior of the partial sums of the truncated heavy tailed model (1.2) is concerned,

In this paper, we establish improved effective irra- tionality measures for certain numbers of the form √ 3 n , using approximations obtained from hypergeometric functions..

In this paper we study the structure of the projec- tions of the finite cutting segments corresponding to unimodular substitutions over a two-letter alphabet.. We show that such

The asymptotic convergence of paths given by the asip (log) then allows these results to pass over from the self-similar processes to the coordinate-changed random walk, by Lemma 6.1

Bertoin [4, 5] gave a different approach to obtain the same fragmentation processes, by using partitions of intervals induced by some bridges with exchangeable increments (the

In section 4 we use this coupling to show the uniqueness of the stationary interface, and then finish the proof of theorem 12. Stochastic compactness for the width of

Figure 3: The mean and the variance of the number of dominating records in low dimensional random samples.. In each model, the expected number approaches 1 very fast as d increases

A conve- nient starting hypothesis which would explain the ubiquity of Lagrangian theories is to consider all successful Lagrangian theories as effective theories arising from
