关于Eisenstein型多重级数

On multiple series of Eisenstein type

Henrik Bachmann, Hirofumi Tsumura

摘要:

本文的目的是研究某些可视为Eisenstein级数多重模拟的多重级数。作为先前的研究,第二名作者考虑了爱森斯坦级数的双重类似物,并将其表示为普通爱森斯坦级数的多项式。这一事实是来自无穷级数的分析观察涉及双曲函数这是基于研究柯西,也拉马努金。本文证明了这些级数之间的一个显式关系式。本文利用Gangl,Kaneko和Zagier提出的多重级数的部分分式分解技术,给出了这一事实的另一种证明。用同样的方法,我们进一步证明了这一事实的某种多重类比,并给出了一些显式公式的例子。最后,我们给出了几个关于我们的结果与以前关于含双曲函数的无穷级数的工作之间关系的注记。

英文摘要:

The aim of this paper is to study certain multiple series which can be regarded as multiple analogues of Eisenstein series. As a prior research, the second-named author considered double analogues of Eisenstein series and expressed them as polynomials in terms of ordinary Eisenstein series. This fact was derived from the analytic observation of infinite series involving hyperbolic functions which were based on the study of Cauchy, and also Ramanujan. In this paper, we prove an explicit relation formula among these series. This gives an alternative proof of this fact by using the technique of partial fraction decompositions of multiple series which was introduced by Gangl, Kaneko and Zagier. By the same method, we further show a certain multiple analogue of this fact and give some examples of explicit formulas. Finally we give several remarks about the relation between our present result and the previous work for infinite series involving hyperbolic functions.
