关于$\mathbb C\mathbb P^1$上有理向量场的注记

Remarks on rational vector fields on $\mathbb C\mathbb P^1$

Martin Klimeš, Christiane Rousseau

摘要:

本文引入几何工具来研究$\mathbb C\mathbb P^1$上给定次数的有理向量场族。对于这样一个参数族的一般向量场,我们关联几个几何对象:周期边形、星域和平移曲面。这些对象一般化了在多项式向量场上的先前工作中引入的具有相同名称的对象。它们被用来描述家庭内部的分歧。我们专门研究次数为$4$的有理向量场的情形。

英文摘要:

In this paper we introduce geometric tools to study the families of rational vector fields of a given degree over $\mathbb C\mathbb P^1$. To a generic vector field of such a parametric family we associate several geometric objects: a periodgon, a star domain and a translation surface. These objects generalize objects with the same name introduced in previous works on polynomial vector fields. They are used to describe the bifurcations inside the families. We specialize to the case of rational vector fields of degree $4$.
