【Abstract】 In this paper a study of the periodic solution of linpar autonomous neutral differntial equations with delays in Presented. Using the theory of Fourier series and matrix, some necessary and sufficient conditions that ensure the existence and uniqueness of the continuous differential periodic solution is obtained. The results are found to be an improvement over priviously aviable results for linear autonomous neutral differential equations.更多还原
