摘要
利用Mawhin方法 ,在限制条件较弱的情况下 ,讨论了具有周期扰动的n维时滞Li啨ｎａｒｄ型方程 ¨x+ ddtF(x) +gradG(x(t-T) ) =e(t,x)的周期解 。
With the help of Mawhin's solution,this paper illustrates the existence of periodic solutions for the n dimensional Liénard equation with delay + d d t grad F(x)+ grad G(x(t-T))=e(t,x) and provides the sufficient conditions of the equation
