A Complete Expression of the Asymptotic Solution of Differential Equation With Three-Turning Points
-
Abstract: In this paper,a second order linear ordinary differential equation with three-turning points is studied.This equation is as follows and λ is a large parameter,but . By using JL function,the complete expression of the formal uniformly valid asymptotic solutions of the equation near turning point is obtained.
