# Trace formulae for Schrodinger operators on metric graphs with applications to recovering matching conditions

@article{Ershova2014TraceFF, title={Trace formulae for Schrodinger operators on metric graphs with applications to recovering matching conditions}, author={Yulia Yu. Ershova and Alexander V. Kiselev}, journal={arXiv: Mathematical Physics}, year={2014} }

The paper is a continuation of the study started in \cite{Yorzh1}. Schrodinger operators on finite compact metric graphs are considered under the assumption that the matching conditions at the graph vertices are of $\delta$ type. Either an infinite series of trace formulae (provided that edge potentials are infinitely smooth) or a finite number of such formulae (in the cases of $L_1$ and $C^M$ edge potentials) are obtained which link together two different quantum graphs under the assumption…
