The spectral problem and *-representations of algebras associated with Dynkin graphs

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/71991We study the connection between *-representations of algebras associated with graphs, locally-scalar graph representations and the problem about the spectrum of a sum of two Hermitian operators. For algebras associated with Dynkin graphs we give an explicit description of the parameters for which there are irreducible representations and an algorithm for contructing these representations.16 pagesRepresentation Theory16G20;16W10The spectral problem and *-representations of algebras associated with Dynkin graphstext
