有限域上Waring问题的精确解

Exact solutions to Waring's problem for finite fields

Arne Winterhof, Christiaan van de Woestijne

摘要:

Waring函数$g(k,q)$度量了在$q$元素的域中对$k$次幂的Waring问题的难度。它的计算似乎是困难的,许多部分结果已经公布,特别是上界的某些地区的$k$ - $q$ -平面。本文计算了两个指数域偶无限族的$g(k,q)$的精确值。其中,与$q$相比,$k$较大。我们使用一种新的证明方法,主要是组合的性质。

英文摘要:

The Waring function $g(k,q)$ measures the difficulty of Waring's problem for $k$th powers in the field of $q$ elements. Its calculation seems to be difficult, and many partial results have been published, notably upper bounds for certain regions of the $k$-$q$-plane. In this paper, we compute the exact value of $g(k,q)$ for two infinite families of exponent-field pairs. In these, $k$ is large compared to $q$. We use a new method of proof that is mainly combinatorial in nature.
