Abstract
Good semigroups form a class of submonoids of containing the value semigroups of curve singularities. In this article, we describe a partition of the complement of good semigroup ideals. As main application, we describe the Apéry sets of good semigroups with respect to arbitrary elements. This generalizes to any the results in the study of D’Anna et al., which are proved in the case d = 2 and only for the standard Apéry set with respect to the smallest nonzero element. Several new results describing good semigroups in are also provided.

好的半群理想和 Apéry 集的补集的划分
摘要
好的半群形成一类子幺半群 包含曲线奇异点的值半群。在本文中,我们描述了良好半群理想的补集的划分。作为主要应用,我们描述了关于任意元素的好半群的 Apéry 集。这推广到任何D'Anna 等人的研究结果在d = 2的情况下得到证明,并且仅适用于关于最小非零元素的标准 Apéry 集。描述良好半群的几个新结果 还提供。
