Singular Weyl-Titchmarsh-Kodaira theory for one-dimensional Dirac operators
Rainer Brunnhuber, Jonathan Eckhardt, Aleksey Kostenko +1
We develop singular Weyl-Titchmarsh-Kodaira theory for one-dimensional Dirac operators. In particular, we establish existence of a spectral transformation as well as local Borg-Mar…

A coupling problem for entire functions and its application to the long-time asymptotics of integrable wave equations
Jonathan Eckhardt, Gerald Teschl
We propose a novel technique for analyzing the long-time asymptotics of integrable wave equations in the case when the underlying isospectral problem has purely discrete spectrum.…

An inverse spectral problem for a star graph of Krein strings
Jonathan Eckhardt
We solve an inverse spectral problem for a star graph of Krein strings, where the known spectral data comprises the spectrum associated with the whole graph, the spectra associated…
