An approximation to $δ^{'}$ couplings on graphs

Taksu Cheon, Pavel Exner

We discuss a general parametrization for vertices of quantum graphs and show, in particular, how the $δ_{s}^{'}$ and $δ^{'}$ coupling at an $n$ edge vertex can be approximated by means of…

A lower bound to the spectral threshold in curved tubes

P. Exner, P. Freitas, D. Krejcirik

We consider the Laplacian in curved tubes of arbitrary cross-section rotating together with the Frenet frame along curves in Euclidean spaces of arbitrary dimension, subject to Dir…
