Abstract: In this paper, the high order delay Duffing equation ax(2n)+bx+g(x(t-τ)) =p(t) are considered,using the theory of coincidence degree, the sufficient condition for its there being at least a 2π-periodic solution is obtained.

Key words: Duffing , equation;periodic , solution;coincidence , degree
