We study the dynamical behaviour of polynomial hamiltonian planar vector fields. Particularly we analyze the structure of finite and infinite critical points and we obtain the best upper bound of the number of centers and of the number of saddles that a system of this type can exhibit, depending on
The Lotka-Volterra system of autonomous di erential equations consists in three homogeneous polynomial equations of degree 2 in three variables. This system, or the corresponding vector ΓΏeld LV (A; B; C), depends on three non-zero (complex) parameters and may be written as LV (A; B; C) = Vx@x + Vy@y
