有限环的Carlitz-von Staudt型定理

A Carlitz-von Staudt type theorem for finite rings

Apoorva Khare, Akaki Tikaradze

摘要:

本文计算了任意有限酉环$R$上的$k$次幂和(对所有$k>0$).这统一和扩展了Brawley,Carlitz和Levine关于矩阵环的工作[Duke Math. J. 1974],有限域和有限循环群的民间结果,以及Grau和Oller-Marcen关于交换环的更一般的最近结果[有限域Appl. 2017]。作为应用,我们解决了一个猜想,由Ayuso,Grau,Oller-Marcen,和Rua的zeta值的矩阵环有限交换环[Internat. J.代数计算2017年]。我们通过多项式环上的zeta值进一步改写了我们的主要结果,并通过对一大类有限交换环上的交换不变多项式进行分类而结束。

英文摘要:

We compute the $k$th power-sums (for all $k>0$) over an arbitrary finite unital ring $R$. This unifies and extends the work of Brawley, Carlitz, and Levine for matrix rings [Duke Math. J. 1974], with folklore results for finite fields and finite cyclic groups, and more general recent results of Grau and Oller-Marcen for commutative rings [Finite Fields Appl. 2017]. As an application, we resolve a conjecture by Fortuny Ayuso, Grau, Oller-Marcen, and Rua on zeta values for matrix rings over finite commutative rings [Internat. J. Algebra Comput. 2017]. We further recast our main result via zeta values over polynomial rings, and end by classifying the translation-invariant polynomials over a large class of finite commutative rings.
