欧拉常数的近似

Approximations to Euler's constant

Kh. Hessami Pilehrood, T. Hessami Pilehrood

摘要:

本文研究了如何用调和数和调和数的线性型对欧拉常数$γ=\lim_{n\to\infty}S_n,$(其中$S_n=\sum_{k=1}^n\frac{1}{n}-\log(n+1),$)进行良好的逼近. 1995年,C. Elsner表明,如果将$S_n$替换为具有整数系数的$S_n$的线性组合,则序列$S_n$的缓慢收敛可以得到显著改善。本文考虑序列$S_n$的更一般的线性变换,建立了序列$γ.$的新的加速收敛公式。我们的估计加强和推广了Elsner,Rivoal和作者的结果。

英文摘要:

We study a problem of finding good approximations to Euler's constant $γ=\lim_{n\to\infty}S_n,$ where $S_n=\sum_{k=1}^n\frac{1}{n}-\log(n+1),$ by linear forms in logarithms and harmonic numbers. In 1995, C. Elsner showed that slow convergence of the sequence $S_n$ can be significantly improved if $S_n$ is replaced by linear combinations of $S_n$ with integer coefficients. In this paper, considering more general linear transformations of the sequence $S_n$ we establish new accelerating convergence formulae for $γ.$ Our estimates sharpen and generalize recent Elsner's, Rivoal's and author's results.
