AI 中文摘要
针对由约化完全交点集构造的码的最小距离,我们对Tohǎneanu和Van Tuyl提出的猜想给出了肯定解答。尽管该猜想具有技术性,我们证明它可直接从超定多项式方程组经典Bézout界的一个鲜为人知的改进形式导出,为完整起见,本文给出该改进界的自包含证明。此外,我们表明采用相同方法可得到此类码的广义汉明重量界,更一般地,可控制零维完全交点上d次形式求值所得码的最小距离。
英文摘要
We provide a positive answer to a conjecture proposed by Tohǎneanu and Van Tuyl regarding the minimum distance of codes whose underlying set of points is a reduced complete intersection. Despite the technical nature of the conjecture, we show that it follows directly from a not-well-known refinement of the classical Bézout bound for overdetermined polynomial systems. For completeness, this paper presents a self-contained proof of this refined bound. Furthermore, we show that using the same approach, it is possible to obtain a bound on the generalized Hamming weights of such a code and, more generally, to control the minimum distance of the codes obtained by evaluating forms of degree $d$ on the points of a zero-dimensional complete intersection.
