Subnormal operators in strictly cyclic operator algebras

Richard Bolstein and Warren R. Wogen

Vol. 49 (1973), No. 1, 7–11
Abstract

It is shown that a subnormal operator cannot belong to a strictly cyclic and separated operator algebra unless it is normal and has finite spectrum. Further, a subnormal operator not of this type cannot have a strictly cyclic commutant.
