On the limiting absorption principle and spectra of quantum graphs

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/103523The main result of the article is validity of the limiting absorption principle and thus absence of the singular continuous spectrum for compact quantum graphs with several infinite leads attached. The technique used involves Dirichlet-to-Neumann operators.11 pages, 2 figuresMathematical PhysicsSpectral Theory35Q99 (Primary) 35P99, 35P05 (Secondary)On the limiting absorption principle and spectra of quantum graphstext
