| Abstract: | By using the theorem of coincidence degree, existence of periodic solutions for a class of higher order neutral functional differential equation with deviating arguments is studied. Two sufficient conditions for the existence of periodic solutions are obtained. The results have extend and improved the related reports in the literatures. |
