在本研究中,我们构造了正常孤立奇点 x0 X0 的最小局部半通用变形,其中 Ext²O(X0)(Ω(X0), O(X0))x0 = 0,其中 Ω(X0) 是复空间 (X0, O(X0)) 中一维全纯形式的胚芽束。
In this study we construct the minimal locally semiuniversal deformation of a normal isolated singularity x0 X0 for which Ext²O(X0)(Ω(X0), O(X0))x0 = 0, where Ω(X0) is the sheaf of germs of one-dimensional holomorphic forms in the complex space (X0, O(X0)).
