چکیده

After the proof by R. Apéry of the irrationality of ζ(3) in 1976, a number of articles have been devoted to the study of Diophantine properties of values of the Riemann zeta function at positive integers. A survey has been written by S. Fischler for the Bourbaki Seminar in November 2002 [6]. Here, we review more recent results, including contributions by P. Bundschuh, S. Bruiltet, C. Elsner, S. Fischler, S. Gun, M. Hata, C. Krattenthaler, R. Marcovecchio, R. Murty, Yu.V. Nesterenko, P. Philippon, P. Rath, G. Rhin, T. Rivoal, S. Shimomura, I. Shiokawa, C. Viola, W. Zudilin. We plan also to say a few words on the analog of this theory in finite characteristic, with works of G. Anderson, W.D. Brownawell, M. Pappanikolas, D. Thakur, Chieh-Yu Chang, Jing Yu. 1 Special values of the Riemann zeta function Several zeta functions exist, including Riemann zeta function, Multizeta functions, Weierstraß zeta function, those of Fibonacci, Hurwitz, Carlitz, Dedekind, Hasse-Weil, Lerch, Selberg, Witten, Milnor and the zeta functions of dynamical systems. . . 1.1 The Riemann zeta function We first review the Riemann zeta function, which was previously introduced by L. Euler: ζ(s) = ∑ n≥1 1 ns for s ∈ R, s ≥ 2. He showed the Euler product : ζ(s) = ∏ p 1 1− p−s · ∗Notes written by N. Hirata from the text of the slides of the lecture given at the Conference on Analytic number theory and related topics, RIMS, Kyoto, Japan, organized by H. Tsumura. The author wishes to express his deep gratitude to Noriko Hirata and Hirofumi Tsumura.

DIOPHANTINE PROBLEMS FOR q-ZETA VALUES 1

hold. The above defined q-zeta values (1) present several new interesting problems in the theory of diophantine approximations and transcendental numbers; these problems are extensions of the corresponding problems for ordinary zeta values and we state some of them in Section 3 of this note. Our nearest aim is to demonstrate how some recent contributions to the arithmetic study of the numbers ζ...

Hankel Determinants of Zeta Values

We study the asymptotics of Hankel determinants constructed using the values ζ(an + b) of the Riemann zeta function at positive integers in an arithmetic progression. Our principal result is a Diophantine application of the asymptotics.

Transcendence in Positive Characteristic and Special Values of Hypergeometric Functions

We prove a simple transcendence criterion suitable for function field arithmetic. We apply it to show the transcendence of special values at non-zero rational arguments (or more generally, at algebraic arguments which generate extension of the rational function field with less than q places at infinity) of the entire hypergeometric functions in the function field (over Fq) context, and to obtai...

Well-poised Hypergeometric Service for Diophantine Problems of Zeta Values

It is explained how the classical concept of well-poised hypergeometric series and integrals becomes crucial in studing arithmetic properties of the values of Riemann’s zeta function. By these well-poised means we obtain: (1) a permutation group for linear forms in 1 and ζ(4) = π/90 yielding a conditional upper bound for the irrationality measure of ζ(4); (2) a second-order Apéry-like recursion...

Euler’s Constant: Euler’s Work and Modern Developments

This paper has two parts. The first part surveys Euler’s work on the constant γ = 0.57721 · · · bearing his name, together with some of his related work on the gamma function, values of the zeta function, and divergent series. The second part describes various mathematical developments involving Euler’s constant, as well as another constant, the Euler–Gompertz constant. These developments inclu...
