摘要:

本文的主要目的是介绍新的方法,用于研究与弯曲函数相关的组合设计。这些方法基于将有限阿贝尔群上的卷积解释为多维矩阵乘法,并将设计解释为$\mathbb{F}_2^n$的子空间超图的完美着色。我们建立了卷积矩阵的特征函数与子空间超图的完美着色之间的对应关系,证明了子空间超图的完美着色可以用卷积来表征,并且二值特征函数的子空间超图对应于完美着色。作为应用,我们表示部分差集、弯曲和 plateaued 布尔函数、展开、以及强弯曲分区作为卷积矩阵的特征函数和子空间超图的完美着色。我们还找到了某些卷积矩阵在$\mathbb{F}_2^n$和$\mathbb{F}_3^n$上的特征值。

英文摘要:

The main aim of the present paper is to introduce new methods for the study of combinatorial designs related to bent functions. They are based on interpretations of convolution on finite abelian groups as multiplication by a multidimensional matrix and designs as perfect colorings of subspace hypergraphs of $\mathbb{F}_2^n$. We establish a correspondence between eigenfunctions of convolution matrices and perfect colorings of subspace hypergraphs, show that perfect colorings of subspace hypergraphs admit a characterization in terms of convolution and that two-valued eigenfunctions of subspace hypergraphs correspond to perfect colorings. As applications, we represent partial difference sets, bent and plateaued Boolean functions, spreads, and strong bent partitions of $\mathbb{F}_2^n$ as eigenfunctions of convolution matrices and as perfect colorings of subspace hypergraphs. We also find some eigenvalues of convolution matrices over $\mathbb{F}_2^n$ and $\mathbb{F}_3^n$.
