摘要

我们研究“结构化”网格上的多元多项式。首先，我们提出了一个解释，这意味着一个有限的子集的场是结构化的;我们通过一个数值参数，即零点来做到这一点。然后，我们将几个结果——特别是组合Nullstellensatz和系数定理——扩展到结构化网格上的多项式。主要的一点是，网格的结构允许对多项式的程度约束是放松的。

Polynomials over structured grids

We study multivariate polynomials over ‘structured’ grids. Firstly, we propose an interpretation as to what it means for a finite subset of a field to be structured; we do so by means of a numerical parameter, the nullity. We then extend several results – notably, the Combinatorial Nullstellensatz and the Coefficient Theorem – to polynomials over structured grids. The main point is that the structure of a grid allows the degree constraints on polynomials to be relaxed.
