Commutants of nest algebras modulo the compact operators
Research output: Contribution to journal › Journal article › Research › peer-review
Any operator x which commutes modulo the compact operators with a nest algebra is of the form λI+C, where λ is a scalar and C is a compact operator. Any derivation from a nest algebra on a Hilbert space H into the compact operators on H is implemented by a compact operator. Any derivation on a quasitriangular operator algebra is inner.
