I71-R177-UNGS-18182024-12-23T14:30:42Z Unitary operators with decomposable corners Andruchow, Esteban Closed subspace Singular valu decomposition Unitary operator Fil: Andruchow, Esteban. Universidad Nacional de General Sarmiento. Instituto de Ciencias; Argentina. Fil: Andruchow, Esteban. Consejo Nacional de Investigaciones Científicas y Técnicas. Instituto Argentino de Matemática "Alberto P. Calderón"; Argentina. We study pairs (U, L) , where U is a unitary operator in H and L? H is a closed subspace, such that PL0U|L0:L0?L0has a singular value decomposition. Abstract characterizations of this condition are given, as well as relations to the geometry of projections and pairs of projections. Several concrete examples are examined. 2024-12-23T14:30:41Z 2024-12-23T14:30:41Z 2021 info:eu-repo/semantics/article info:ar-repo/semantics/artículo info:eu-repo/semantics/publishedVersion Andruchow, E.
