Inverse Spectral Theory for Sturm-Liouville Operators with Distributional Potentials
Jonathan Eckhardt, Fritz Gesztesy, Roger Nichols +1
We discuss inverse spectral theory for singular differential operators on arbitrary intervals associated with rather general differential expressions o…
Supersymmetry and Schrödinger-type operators with distributional matrix-valued potentials
Jonathan Eckhardt, Fritz Gesztesy, Roger Nichols +1
Building on work on Miura's transformation by Kappeler, Perry, Shubin, and Topalov, we develop a detailed spectral theoretic treatment of Schrödinger operators with matrix-valued p…
Singular Weyl-Titchmarsh-Kodaira Theory for Jacobi Operators
Jonathan Eckhardt, Gerald Teschl
We develop singular Weyl-Titchmarsh-Kodaira theory for Jacobi operators. In particular, we establish existence of a spectral transformation as well as local Borg-Marchenko and Hoch…
Two inverse spectral problems for a class of singular Krein strings
Jonathan Eckhardt
We solve the inverse problem from the spectral measure and the inverse three-spectra problem for the class of singular Krein strings on a finite interval with trace class resolvent…
