where Ξ» > 0 is a parameter and T > 0 is a constant. It is known that if Ξ» 1, then the corresponding solution has boundary layers. In this paper, we characterize Ξ» by the boundary layers of the solution when Ξ» 1 from a variational point of view. To this end, we parameterize a solution pair Ξ» u by a n
We consider some inverse spectral problems associated with the singular Sturm-Liouville equation . . , which is obtained by separation of variables in the 3D radial SchrΓΆdinger equation. One approach to such problems involves the use of almost isospectral transformations, by means of which a reduct
