Hermitian码的零维逼近

A zero-dimensional approach to Hermitian codes

Edoardo Ballico, Alberto Ravagnani

摘要:

本文研究了域上平面平滑曲线上一类求值码的代数几何。特别是,我们提供了一个上同调的双重最小距离的特征。在讨论了平面上零维子格式的一般结果之后,我们着重讨论了Hermitian $s$ -点码的有趣情形,描述了它们的对偶最小权码字的几何结构.

英文摘要:

We study the algebraic geometry of a family of evaluation codes from plane smooth curves defined over any field. In particular, we provide a cohomological characterization of their dual minimum distance. After having discussed some general results on zero-dimensional subschemes of the plane, we focus on the interesting case of Hermitian $s$-point codes, describing the geometry of their dual minimum-weight codewords.
