Let $\mathbb{K}$ be an algebraically closed field. In this paper, we consider the class of smooth plane curves of degree $n+1>3$ over $\mathbb{K}$, containing three points, $P_1,P_2,$ and $P_3$, such that $nP_1+P_2$, $nP_2+P_3$, and $nP_3+P_1$ are di

Finitely curved orbits of complex polynomial vector fields

Autor: Albetã C. Mafra

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 79, Iss 1, Pp 13-16 (2007)

This note is about the geometry of holomorphic foliations. Let X be a polynomial vector field with isolated singularities on C². We announce some results regarding two problems: 1. Given a finitely curved orbit L of X, under which conditions is L al
