Periodic perturbations of quadratic planar polynomial vector fields [PDF]

Anais da Academia Brasileira de Ciências, 2002
In this work are studied periodic perturbations, depending on two parameters, of quadratic planar polynomial vector fields having an infinite heteroclinic cycle, which is an unbounded solution joining two saddle points at infinity.

Twin Vector Fields and Independence of Spectra for Quadratic Vector Fields [PDF]

Journal of Dynamical and Control Systems, 2016
The object of this paper is to address the following question: When is a polynomial vector field on $\mathbb{C}^2$ completely determined (up to affine equivalence) by the spectra of its singularities? We will see that for quadratic vector fields this is not the case: given a generic quadratic vector field there is, up to affine equivalence, exactly one
