A note on Spectral Analysis of Quantum graphs
arXiv:2209.02968
Abstract
We provide an introductory review of some topics in spectral theory of Laplacians on metric graphs. We focus on three different aspects: the trace formula, the self-adjointness problem and connections between Laplacians on metric graphs and discrete graph Laplacians.
