数值半群的算术扩张

The arithmetic extensions of a numerical semigroup

Ignacio Ojeda, José Carlos Rosales

摘要:

本文引入了数值半群扩张的概念。给出了扩张都是算术扩张的数值半群的一个刻划,并给出了计算给定数值半群的算术扩张的整集的一个算法.作为副产品,得到了比例模半群的Frobenius数和亏格的新的显式公式。

英文摘要:

In this paper we introduce the notion of extension of a numerical semigroup. We provide a characterization of the numerical semigroups whose extensions are all arithmetic and we give an algorithm for the computation of the whole set of arithmetic extension of a given numerical semigroup. As by-product, new explicit formulas for the Frobenius number and the genus of proportionally modular semigroups are obtained.
