关于超曲面奇点的Tjurina理想

代数几何 2023-07-11 v2

摘要

全纯函数ff的芽的Tjurina理想是由ff自身及其偏导数生成的O\mathbbmCn,0\mathscr{O}_{\mathbbm{C}^n,0}(即\mathbbmCn\mathbbm{C}^n00点处芽的环)的理想。此处记作T(f)T(f)。理想T(f)T(f)赋予由ff定义的超曲面奇点以(\mathbbmCn,0)(\mathbbm{C}^n,0)的闭子概型结构,是奇点理论中核心关注的对象。在本注记中,我们引入\emph{TT-丰满性}与\emph{TT-相关性},这是任意全纯函数芽理想都易验证的两个性质。这两个性质使我们得到了关于理想IO\mathbbmCn,0I\subset \mathscr{O}_{\mathbbm{C}^n,0}的方程I=T(f)I=T(f)存在解ff的充要条件。
