Abstract

In this paper we introduce geometric tools to study the families of rational vector fields of a given degree over \mathbb C\mathbb P¹. 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.
