Abstract: | In this paper, a second order linear ordinary differential equation with three-turning points is studied. This equation is
as follows whereq
t
(x)=(x-μ
1)(x-μ
2)(x-μ
2)f(x),f(x)≠0,μ
<}μ
2 <μ
3, 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. |
