Linear estimate for the number of limit cycles of a perturbed cubic polynomial differential system

Nonlinear Analysis: Theory, Methods & Applications, 2009
In the focus of this paper is a near-Hamiltonian polynomial system in the form \[ \dot{x}=-y(a_1x+a_0)(b_1y+b_0) + \varepsilon p(x,y), \qquad \dot{y}=x(a_1x+a_0)(b_1y+b_0) + \varepsilon q(x,y), \] where \(a_0,a_1,b_0,b_1\neq0\), \(\varepsilon \geq 0\) is a small real parameter, \(p\) and \(q\) are two arbitrary polynomials of degree \(n\).
