【Abstract】 In this paper we consider the asymptotic expression of the solution of the Cauchy problem for a higher order equation when the limit equation has singularity. In order to construct the asymptotic expression of the solution, the region is divided into three sub-areas. In every small region, the solution of the differential equation is different.更多还原
