Melnikov analysis in a cubic system with a multiple line of critical points

In this paper, the first fourth order Melnikov analyses are applied to find the limit cycles bifurcated from a cubic center under the perturbation of quadratic polynomials in ϵ up to the second order. The upper bounds of the number of limit cycles are given and can be reached.
