On the Commutant of Invertible Positive Operators
Fuad Kittaneh, Carlos S. Kubrusly, Mohammad Sal Moslehian
An important result due to Radjabalipour asserts that if ${A\in\BB(\H)}$ is an invertible positive operator and ${T\in\BB(\H)}$ is arbitrary, then the operator sequence $\{A^{-n}TA…

Structural Properties and Normality Criteria for Subclasses of Normaloid Operators
Hranislav Stanković, Carlos Kubrusly
We investigate structural properties and normality criteria for certain classes of bounded linear operators on a Hilbert space. We show that an operator with polar decompositio…
