Isospectrality for graph Laplacians under the change of coupling at graph vertices: necessary and sufficient conditions

Yulia Ershova, Irina I. Karpenko, Alexander V. Kiselev

Laplace operators on finite compact metric graphs are considered under the assumption that matching conditions at graph vertices are of $δ$ and $δ^{'}$ types. Assuming rational indepe…
