摘要 考察了具有两个偏差变元的广义Liénard型方程,利用重合度理论研究其周期解问题,得到了该方程周期解存在的充分条件,结论丰富了现有文献的结果。 In this paper,tdhe existence of periodic solution for a kind of Liénard equation with two deviating arguments is investigated by applying Mawhin's coincidence degree theory,and some sufficient criteria are established,which improve some known results.
