| Abstract: | In this article,we apply the concept of hyper-order to higher order linear diffierential equations with periodic coefficients,investigate the existence and the form of its subnormal solution,and estimate the growth of all other solutions,and answer the question raised by Gundersen and Steinbart for more general periodic diffierential equations. |
