关于拟齐次函数的模空间

On the moduli space of quasi-homogeneous functions

Leonardo Meireles Câmara, Maria Aparecida Soares Ruas

AI总结:

本文研究了$(\mathbb{C}^2,0)$处约化拟齐次函数解析等价芽的模空间与双Lipschitz等价类的关系,证明了具有常数Henry-Parusiński不变量的非退化函数族是解析平凡的,并得出相同不变量下双Lipschitz类数量有限且存在最大配额。

摘要:

我们将$(\mathbb{C}^2,0)$处约化拟齐次函数的解析等价芽的模空间与其双Lipschitz等价类联系起来。我们证明,任何具有常数Henry-Parusiński不变量的非退化连续(约化)拟齐次函数族是解析平凡的。此外,我们证明在具有相同Henry-Parusiński不变量的拟齐次函数中,只有有限个不同的双Lipschitz类,并为该数目提供了最大配额。

英文摘要:

We relate the moduli space of analytic equivalent germs of reduced quasi-homogeneous functions at $(\mathbb{C}^2,0)$ with their bi-Lipschitz equivalence classes. We show that any non-degenerate continuous family of (reduced) quasi-homogeneous functions with constant Henry-Parusiński invariant is analytically trivial. Further we show that there are only a finite number of distinct bi-Lipschitz classes among quasi-homogeneous functions with the same Henry-Parusiński invariant providing a maximum quota for this number.
