چکیده
|
We investigated the existence of periodic solutions to a kind of non-linear differential equations of third order. we prove two new theorems on the existence of periodic solutions to the equation considered. the technique of proof involves the leray-schauder degree theory. the results obtained include and improve some results found in the literature. © pakistan academy of sciences.
