Uniqueness Results for Schrödinger Operators on the Line with Purely Discrete Spectra
نویسندگان
چکیده
We provide an abstract framework for singular one-dimensional Schrödinger operators with purely discrete spectra to show when the spectrum plus norming constants determine such an operator completely. As an example we apply our findings to prove a new uniqueness results for perturbed quantum mechanical harmonic oscillators. In addition, we also show how to establish a Hochstadt–Liebermann type result for these operators. Our approach is based on the singular Weyl–Titchmarsh theory which is extended to cover the present situation.

Uniqueness Theorems in Inverse Spectral Theory for One-dimensional Schrödinger Operators
New unique characterization results for the potential V (x) in connection with Schrödinger operators on R and on the half-line [0,∞) are proven in terms of appropriate Krein spectral shift functions. Particular results obtained include a generalization of a well-known uniqueness theorem of Borg and Marchenko for Schrödinger operators on the half-line with purely discrete spectra to arbitrary sp...

متن کاملHalf-line Schrödinger Operators with No Bound States
We consider Schödinger operators on the half-line, both discrete and continuous, and show that the absence of bound states implies the absence of embedded singular spectrum. More precisely, in the discrete case we prove that if ∆+V has no spectrum outside of the interval [−2, 2], then it has purely absolutely continuous spectrum. In the continuum case we show that if both −∆+V and −∆−V have no ...
متن کاملLocal Spectral Properties of Reflectionless Jacobi, Cmv, and Schrödinger Operators
We prove that Jacobi, CMV, and Schrödinger operators, which are reflectionless on a homogeneous set E (in the sense of Carleson), under the assumption of a Blaschke-type condition on their discrete spectra accumulating at E, have purely absolutely continuous spectrum on E.
متن کاملSingular Continuous Spectrum of Half-line Schrödinger Operators with Point Interactions on a Sparse Set
We say that a discrete set X = {xn}n∈N0 on the half-line 0 = x0 < x1 < x2 < x3 < · · · < xn < · · · < +∞ is sparse if the distances ∆xn = xn+1−xn between neighbouring points satisfy the condition ∆xn ∆xn−1 → +∞. In this paper half-line Schrödinger operators with point δand δ′-interactions on a sparse set are considered. Assuming that strengths of point interactions tend to ∞ we give simple suff...
