Eulàlia Montoro[en] This project studies the following problem: If the eigenvalues of two Hermitian matrices are known, we want to find the eigenvalues of the sum of these two matrices. The necessary conditions that we will find are inequalities between the different eigenvalues. Horn’s conjecture says that these necessary conditions are, in fact, sufficient.51 p.application/pdfcatcc-by-nc-nd (c) Montse Digon Quintillà, 2024http://creativecommons.org/licenses/by-nc-nd/3.0/es/Àlgebra linealDesigualtats (Matemàtica)Desigualtats matricialsMatrius (Matemàtica)Treballs de fi de grauLinear algebraInequalities (Mathematics)Matrix inequalitiesMatricesBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
