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…
Weak Quasistability and Rajchman measures
Carlos Kubrusly
It is shown that weak quasistability does not imply power boundedness, but coercive power unbounded operators cannot be weakly quasistable.\ Although a finite measure over the unit…
An Exposition on Weak Stability of Operators
C. S. Kubrusly
This is an expository-survey on weak stability of bounded linear operators acting on normed spaces in general and, in particular, on Hilbert spaces. The paper gives a comprehensive…
Weak Supercyclicity -- An Expository Survey
Carlos S. Kubrusly
This is an exposition on supercyclicity and weak supercyclicity, especially designed to advance further developments in weakly supercyclicity, which is a recent research field show…
Convergence of power sequences of operators via their stability
Zenon Jan Jabłoński, Il Bong Jung, Carlos Kubrusly +1
This paper is concerned with the convergence of power sequences and stability of Hilbert space operators, where "convergence" and "stability" refer to weak, strong and norm topolog…
Forms of biisometric operators and biorthogonality
B. P. Duggal, C. S. Kubrusly
The paper proves two results involving a pair (A,B) of P-biisometric or (m,P)-biisometric Hilbert-space operators for arbitrary positive integer m and positive operator P. It is sh…
