摘要
For upper triangular operators with nonnegative real part: we derive generalized Herglotz representation theorems in which the main operator is coisometric, isometric, or unitary. The proofs are based on the representation theorems for upper triangular contractions considered earlier by D. Alpay and Y. Peretz. (C) 1999 Academic Press.
