奇异性叶状结构的 Nash 消解序列

微分几何 2026-04-28 v2

摘要

我们通过将 Nash 修饰应用于奇异性叶状结构的泛 Lie \infty-代数,构造了奇异性叶状结构的一列爆破 (M~i,πi)iN0(\widetilde M_i,\pi_i)_{i\in \mathbb N_0}。当 i=0i=0 时,我们恢复了 Sinan Sert"oz 引入的爆破;当 i=1i=1 时,我们恢复了 Omar Mohsen 提出的概念。一个重要特征是:任意奇异性叶状结构在一次爆破后都成为 Debord 叶状结构(=射影奇异性叶状结构)。文中亦给出示例。

The title has been changed. The introduction has been extended. A new section on the smoothness of the Nash blowup has been added. The main results have been clarified. These main results are taken from Chapter 7 of my PhD thesis
