Define the periodic weighted operator Ty=&\ &2 ( \ 2 y$)$ in L 2 (R, \(x) 2 dx). Suppose a function \ # W 2 1 (RΓZ) is 1-periodic real positive, \(0)=1, and let q=\$Γ\ # L 2 (0, 1). The spectrum of T consists of intervals , n 1, be the Dirichlet eigenvalue of the equation & y"&2qy$=z 2 y, y(0)=y(1)
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
