| Abstract: | By applying method of topology degree theory,some conclusions have been drawn on the existence of the periodic solution for a class of high-order differential equations with delays.The existence of periodic solution for the related system was discussed on the basis of the continuation theorem of Mawhin and the theorem of Arzela-Ascoli as well as some analysis techniques. |
