| Abstract: | In this paper, we mainly study the number of limit cycles for a quintic Li"{e}nard system under polynomial perturbations. In some cases, we give new estimations for the lower bound of the maximal number of limit cycles. |
| Keywords: | Limit cycle, bifurcation, Li" {e}nard system, Melnikov function. |
