Bounded Eigenfunctions and Absolutely Continuous Spectra for One-dimensional Schrödinger Operators
نویسنده
چکیده
We provide a short proof of that case of the Gilbert-Pearson theorem that is most often used: That all eigenfunctions bounded implies purely a.c. spectrum. Two appendices illuminate Weidmann's result that potentials of bounded variation have strictly a.c. spectrum on a half-axis. 5

Wkb Asymptotic Behavior of Almost All Generalized Eigenfunctions for One-dimensional Schrödinger Operators with Slowly Decaying Potentials
We prove the WKB asymptotic behavior of solutions of the differential equation −d2u/dx2 + V (x)u = Eu for a.e. E > A where V = V1 + V2, V1 ∈ L(R), and V2 is bounded from above with A = lim supx→∞ V (x), while V ′ 2(x) ∈ L(R), 1 ≤ p < 2. These results imply that Schrödinger operators with such potentials have absolutely continuous spectrum on (A,∞). We also establish WKB asymptotic behavior of s...
متن کاملGeneralized eigenfunctions of relativistic Schrödinger operators in two dimensions
Generalized eigenfunctions of the two-dimensional relativistic Schrödinger operator H = √ −∆ + V (x) with |V (x)| ≤ C〈x〉−σ, σ > 3/2, are considered. We compute the integral kernels of the boundary values R± 0 (λ) = ( √ −∆− (λ± i0))−1, and prove that the generalized eigenfunctions φ±(x, k) are bounded on R x × {k | a ≤ |k| ≤ b}, where [a, b] ⊂ (0,∞)\σp(H), and σp(H) is the set of eigenvalues of ...
متن کاملPersistence under Weak Disorder of AC Spectra of Quasi-Periodic Schrödinger operators on Trees Graphs
We consider radial tree extensions of one-dimensional quasi-periodic Schrödinger operators and establish the stability of their absolutely continuous spectra under weak but extensive perturbations by a random potential. The sufficiency criterion for that is the existence of Bloch-Floquet states for the one dimensional operator corresponding to the radial problem.
متن کاملSpectral Properties of a Class of Reflectionless Schrödinger Operators
We prove that one-dimensional reflectionless Schrödinger operators with spectrum a homogeneous set in the sense of Carleson, belonging to the class introduced by Sodin and Yuditskii, have purely absolutely continuous spectra. This class includes all earlier examples of reflectionless almost periodic Schrödinger operators. In addition, we construct examples of reflectionless Schrödinger operator...
متن کاملEigenfunctions, Transfer Matrices, and Absolutely Continuous Spectrum of One-dimensional Schrödinger Operators
on L(R ) (and its half-line problem, H+, on L2(0,∞) with u(0) = 0 boundary conditions). We will focus on a new approach to the absolutely continuous spectrum σac(h) and, more generally, Σac(h), the essential support of the a.c. part of the spectral measures. What is new in our approach is that it relies on estimates on the transfer matrix, that is, the 2× 2 matrix TE(n,m) which takes (u(m+1) u(...
