实Milnor纤维化对拟齐次奇点的等价性

Equivalence of real Milnor's fibrations for quasi homogeneous singularities

R. Araujo dos Santos

摘要:

我们将利用欧拉向量场来证明,对于具有孤立临界值的实拟齐次奇点,由于存在零能级的“薄”空心管中的Milnor纤维化和球面中“环节”的补中的纤维化,它们是等价的。此外,为了做到这一点,我们明确地描述了投影$\frac{f}{\|f\|}:S_ε^{m}\setminus K_ε\to S^{1}$的临界点,其中$K_ε$是奇异的链接。

英文摘要:

We are going to use the Euler's vector fields in order to show that for real quasi-homogeneous singularities with isolated critical value, the Milnor's fibration in a "thin" hollowed tube involving the zero level and the fibration in the complement of "link" in sphere are equivalents, since they exist. Moreover, in order to do that, we explicitly characterize the critical points of projection $\frac{f}{\|f\|}:S_ε^{m}\setminus K_ε\to S^{1}$, where $K_ε$ is the link of singularity.
