Keywords:limit cycle, bifurcation, Lienard system, Melnikov function
Abstract:
      In this paper, we mainly study the number of limit cycles for a quintic Lienard system under polynomial perturbations. In some cases, we give new estimations for the lower bound of the maximal number of limit cycles.
