摘要

求任何数值半群 S 的弗罗贝尼斯数和属是一个众所周知的公开问题。同样，如何表达数值半群的商的弗罗贝尼斯数和属也是一个研究课题。本文通过枚举各类数字半群的希尔伯特数列，展示了由以下数列之一生成的数字半群商的属数表达式：算术级数、几何级数和毕达哥拉斯三重数。

The genus of a quotient of several types of numerical semigroups

Finding the Frobenius number and the genus of any numerical semigroup $S$ is a well-known open problem. Similarly, it has been studied how to express the Frobenius number and the genus of a quotient of a numerical semigroup. In this paper, by enumerating the Hilbert series of each type of numerical semigroup, we show an expression for the genus of a quotient of numerical semigroups generated by one of the following series: arithmetic progression, geometric series, and Pythagorean triple.
