Multiple periodic solutions of high order differential delay equations with 2k−1 $2k-1$ lags

Abstract In this paper, we study the periodic solutions of high order differential delay equations with 2k−1 $2k-1$ lags. The 4k-periodic solutions are obtained by using the variational method and the method of Kaplan–Yorke coupling system. These are new types of differential delay equations compare...
