On the hot spots of quantum trees

James Kennedy, Jonathan Rohleder

We show that any second eigenfunction of the Laplacian with standard vertex conditions on a metric tree graph attains its extremal values only at degree one vertices, and give an e…

Surgery principles for the spectral analysis of quantum graphs

Gregory Berkolaiko, James B. Kennedy, Pavel Kurasov +1

We present a systematic collection of spectral surgery principles for the Laplacian on a metric graph with any of the usual vertex conditions (natural, Dirichlet or -type), whic…

The damped wave equation with unbounded damping

Pedro Freitas, Petr Siegl, Christiane Tretter

We analyze new phenomena arising in linear damped wave equations on unbounded domains when the damping is allowed to become unbounded at infinity. We prove the generation of a cont…
