平面赋值集合的Poincare级数

Poincare series of collections of plane valuations

A. Campillo, F. Delgado, S. M. Gusein-Zade, F. Hernando

AI总结:

本文给出了原点为中心的二变量函数芽环上一般赋值集合的Poincare级数公式,并证明了该级数决定集合拓扑这一命题的推广。

摘要:

在早期论文中,给出了由对应于(可约)平面曲线奇点的赋值集合和除子赋值集合定义的二变量函数芽环上多指标过滤的Poincare级数公式。证明了除子赋值集合的Poincare级数决定除子集合的拓扑。本文给出了原点为中心的二变量函数芽环上一般赋值集合的Poincare级数公式,并证明了该级数决定集合拓扑这一命题的推广。

英文摘要:

In earlier papers there were given formulae for the Poincare series of multi-index filtrations on the ring of germs of functions of two variables defined by collections of valuations corresponding to (reducible) plane curve singularities and by collections of divisorial ones. It was shown that the Poincare series of a collection of divisorial valuations determines the topology of the collection of divisors. Here we give a formula for the Poincare series of a general collection of valuations on the ring of germs of functions of two variables centred at the origin and prove a generalization of the statement that the Poincare series determines the topology of the collection.
