加权齐次曲面奇点的Bi-Lipschitz几何

Bi-Lipschitz geometry of weighted homogeneous surface singularities

Lev Birbrair, Alexandre Fernandes, Walter D. Neumann

摘要:

我们证明了加权齐次复曲面奇点是度量圆锥的(即,bi-Lipschitz等价于一个度量锥),只有当它的两个最低权重相等时。我们还给出了一个例子,一对加权齐次复杂的表面奇点,拓扑等价,但不bi-Lipschitz等价。

英文摘要:

We show that a weighted homogeneous complex surface singularity is metrically conical (i.e., bi-Lipschitz equivalent to a metric cone) only if its two lowest weights are equal. We also give an example of a pair of weighted homogeneous complex surface singularities that are topologically equivalent but not bi-Lipschitz equivalent.
