在本文中,我们引入了理想和循环的概念,它继承了有理奇点上的整体封闭理想的良好性质。作为一个应用,我们证明了二维 Gorenstein 正常局部环的良好理想的存在。此外,我们对二维简单椭圆奇点的所有乌尔里希理想进行了分类。
In this paper, we introduce the notion of-ideals and-cycles, which inherits nice properties of integrally closed ideals on rational singularities. As an application, we prove an existence of good ideals for two-dimensional Gorenstein normal local rings. Moreover, we classify all Ulrich ideals for two-dimensional simple elliptic singularities.
