A Unified Study on the Cyclicity of Period Annulus of the Reversible Quadratic Hamiltonian Systems

Journal of Dynamics and Differential Equations, 2004
In this interesting paper, the authors investigate the cyclicity of the period annulus of reversible quadratic Hamiltonian systems under quadratic perturbations. This interesting problem has been extensively studied by serval authors for different cases based on different methods.

The cyclicity of period annulus of a quadratic reversible Lotka–Volterra system

Nonlinearity, 2009
We prove that by perturbing the periodic annulus of the quadratic polynomial reversible Lotka–Volterra differential system , , inside the class of all quadratic polynomial differential systems we can obtain at most two limit cycles.
