复代数芽的分离集、度量切锥及其应用

Separating sets, metric tangent cone and applications for complex algebraic germs

Lev Birbrair, Alexandre Fernandes, Walter D Neumann

摘要:

给出了一个解释,最初令人惊讶的普遍存在的分离集在正常的复杂的表面胚芽。它表明,他们是相当普遍的,在更高的维度。描述了Bernig和Lytchak的度量切锥的几何与分离集之间的关系。此外,分离集被用来表明,内Lipschitz型不需要在一个家庭的正常复杂的表面芽常拓扑常数。

英文摘要:

An explanation is given for the initially surprising ubiquity of separating sets in normal complex surface germs. It is shown that they are quite common in higher dimensions too. The relationship between separating sets and the geometry of the metric tangent cone of Bernig and Lytchak is described. Moreover, separating sets are used to show that the inner Lipschitz type need not be constant in a family of normal complex surface germs of constant topology.
