Weyl Solutions and J-selfadjointness for Dirac operators

B. Malcolm Brown, Martin Klaus, Mark Malamud +2

We consider a non-selfadjoint Dirac-type differential expression \begin{equation} D(Q)y:= J_n \frac{dy}{dx} + Q(x)y, \quad\quad\quad (1) \end{equation} with a non-selfadjoint poten…

Spectral results for perturbed periodic Jacobi matrices using the discrete Levinson technique

Edmund Judge, Sergey Naboko, Ian Wood

For an arbitrary Hermitian period- Jacobi operator, we assume a perturbation by a Wigner-von Neumann type potential to devise subordinate solutions to the formal spectral equati…
