Distinguishing co-spectral quantum graphs by scattering
Delio Mugnolo, Vyacheslav Pivovarchik
We propose a simple method for resolution of co-spectrality of Schrödinger operators on metric graphs. Our approach consists of attaching a lead to them and comparing the -funct…

Dirichlet-Neumann inverse spectral problem for a star graph of Stieltjes strings
Vyacheslav Pivovarchik, Natalia Rozhenko, Christiane Tretter
We solve two inverse spectral problems for star graphs of Stieltjes strings with Dirichlet and Neumann boundary conditions, respectively, at a selected vertex called root. The root…
