数值半群与码

Numerical Semigroups and Codes

Maria Bras-Amorós

摘要:

一个数值半群是N中包含0的子集,在加法下是闭的,并且在N中有有限补。数值半群的一个重要例子是曲线上一点的Weierstrass半群。在代数几何码理论中,Weierstrass半群对于定义最小距离的界以及定义码的维数的改进是至关重要的。我们提出了这些应用和一些理论问题的分类,特征和计数的数值半群。

英文摘要:

A numerical semigroup is a subset of N containing 0, closed under addition and with finite complement in N. An important example of numerical semigroup is given by the Weierstrass semigroup at one point of a curve. In the theory of algebraic geometry codes, Weierstrass semigroups are crucial for defining bounds on the minimum distance as well as for defining improvements on the dimension of codes. We present these applications and some theoretical problems related to classification, characterization and counting of numerical semigroups.
