Liftings and invariant subspaces of Hankel operators

Year: 2026

Type: article

Abstract: We prove a Hankel-variant commutant lifting theorem. This also uncovers the complete structure of the Beurling-type reducing and invariant subspaces of Hankel operators. Kernel spaces of Hankel operators play a key role in the analysis.
