Abstract

The cyclicity of the period annulus of a quadratic reversible and non-Hamiltonian system under quadratic perturbations is studied. The centroid curve method and other mathematical techniques are combined to prove that the related Abelian integral has at most two zeros. This gives a proof of Conjecture 1 in [8] for one case.

Keywords:

A quadratic reversible and non-Hamiltonian system,
a period annulus,
limit cycles,
cyclicity.
