Quadratic Hamiltonian Vector Fields

Journal of Differential Equations, 1994
Let H be a cubic polynomial in two variables over R. Then H defines a quadratic Hamiltonian vector field (∂H/∂y, − ∂H/∂x). The purpose of this paper is to prove that there are exactly 28 non-equivalent topologic phase portraits of quadratic Hamiltonian ...

Hilbert′s 16th Problem for Quadratic Vector Fields

Journal of Differential Equations, 1994
We discuss here a systematic approach towards a positive answer to Hilbert's 16th problem for quadratic systems, namely the existence of a uniform bound for the number of limit cycles of a quadratic system. The method is the following: describe the limit

Perturbations of the non-generic quadratic Hamiltonian vector fields with hyperbolic segment [PDF]

Bulletin Des Sciences Mathematiques, 2001
The paper deals with the non-generic quadratic Hamiltonian vector fields with hyperbolic segment. It is proved that in this situation the cyclicity of period annulus under quadratic perturbation is equal to ...
