J Eckhardt, F Gesztesy, R Nichols, G Teschl - arXiv preprint arXiv …, 2012 - arxiv.org
We systematically develop Weyl-Titchmarsh theory for singular differential operators on
arbitrary intervals $(a, b)\subseteq\mathbb {R} $ associated with rather general differential …

Inverse spectral problems for Sturm–Liouville operators with singular potentials

RO Hryniv, YV Mykytyuk - Inverse Problems, 2003 - iopscience.iop.org
The inverse spectral problem is solved for the class of Sturm–Liouville operators with
singular real-valued potentials from the space W 2− 1 (0, 1). The potential is recovered via …

Representation of solutions to the one-dimensional Schrödinger equation in terms of Neumann series of Bessel functions

VV Kravchenko, LJ Navarro, SM Torba - Applied Mathematics and …, 2017 - Elsevier
A new representation of solutions to the equation− y′′+ q (x) y= ω 2 y is obtained. For
every x the solution is represented as a Neumann series of Bessel functions depending on …

On spectral theory for Schrödinger operators with strongly singular potentials

F Gesztesy, M Zinchenko - Mathematische Nachrichten, 2006 - Wiley Online Library
We examine two kinds of spectral theoretic situations: First, we recall the case of self-adjoint
half-line Schrödinger operators on [a,∞), a∈ ℝ, with a regular finite end point a and the …

Criteria for existence of Riesz bases consisting of root functions of Hill and 1D Dirac operators

P Djakov, B Mityagin - Journal of Functional Analysis, 2012 - Elsevier
We study the system of root functions (SRF) of Hill operator Ly=− y ″+ vy with a singular

Half-inverse spectral problems for Sturm–Liouville operators with singular potentials

RO Hryniv, YV Mykytyuk - Inverse problems, 2004 - iopscience.iop.org
The half-inverse spectral problem for a Sturm–Liouville operator consists in reconstruction of
this operator from its spectrum and half of the potential. We give the necessary and sufficient …

Inverse problems for Sturm—Liouville operators with potentials in Sobolev spaces: Uniform stability

AM Savchuk, AA Shkalikov - Functional Analysis and Its Applications, 2010 - Springer
Two inverse problems for the Sturm-Liouville operator Ly= sy ″+ q (x) y on the interval [0, fy]

On the uniform stability of recovering sine-type functions with asymptotically separated zeros

SA Buterin - Mathematical Notes, 2022 - Springer
We obtain the uniform stability of recovering entire functions of special form from their zeros.
To such a form, we can reduce the characteristic determinants of strongly regular differential …
