dc.description.abstract	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.
