关于Dirichlet $L$值的线性无关性

On linear independence of Dirichlet $L$ values

Sanoli Gun, Neelam Kandhil, Patrice Philippon

摘要:

对于固定整数$k>1$和变化的$χ$,$L(k, χ)$的线性无关性的研究关键地依赖于$k$相对于$χ$的奇偶性。这已经被一些作者研究了Dirichlet字符$χ$的一个固定的模和具有相同的奇偶性作为$k$。本文的重点是将这种调查的家庭Dirichlet字符模不同的两两互质自然数。所得到的周围数字段之间的相互作用带来了新的技术问题和复杂性,迄今为止,在固定模数的上下文中没有(因此,单个数字段潜伏在背景中)。这需要非常仔细和动手处理的算术复合数领域,我们在这项工作中进行。我们的研究结果扩展了第一作者Murty Rath的早期作品以及冈田,Murty Saradha和Hamahata的作品。

英文摘要:

The study of linear independence of $L(k, χ)$ for a fixed integer $k>1$ and varying $χ$ depends critically on the parity of $k$ vis-à-vis $χ$. This has been investigated by a number of authors for Dirichlet characters $χ$ of a fixed modulus and having the same parity as $k$.The focal point of this article is to extend this investigation to families of Dirichlet characters modulo distinct pairwise co-prime natural numbers. The interplay between the resulting ambient number fields brings in new technical issues and complications hitherto absent in the context of a fixed modulus (consequently a single number field lurking in the background). This entails a very careful and hands-on dealing with the arithmetic of compositum of number fields which we undertake in this work. Our results extend earlier works of the first author with Murty-Rath as well as works of Okada, Murty-Saradha and Hamahata.
