Shaowen Yao, Wenjie Li, Zhibo Cheng

• In this paper, we consider the nondegeneracy of a Liénard equation x(t) + f (x(t))x (t) + a(t)x(t) = 0.

  Besides, by nondegenerate results and Manásevich-Mawhin continuation theorem, we prove the existence and uniqueness of periodic solution of the related Liénard equation.
