چکیده
|
We study the multiplicity of periodic solutions of nonautonomous delay differential equations which are asymptotically linear both at zero and at infinity. by making use of a theorem of benci,some sufficient conditions are obtained to guarantee the existence of multiple periodic solutions. © 2011 huafeng xiao and bo zheng.
