Unitary parts of Toeplitz operators with operator-valued symbols

Year: 2025

Type: article

Abstract: Motivated by the canonical decomposition of contractions on Hilbert spaces, we investigate when contractive Toeplitz operators on vector-valued Hardy spaces on the unit disc admit a non-zero reducing subspace on which their restriction is unitary. We
