Quasi-contractivity, Stability and convergence of WCT operators
Y. Estaremi, Z. Huang
In this paper we characterize quasi-contraction, stable and convergent weighted conditional type (WCT) operators on . Indeed we provide equivalent conditions for quasi-cont…

On the Deddens algebras of a class of bounded operators
Z. Huang, Y. Estaremi, S. Shimi
In this paper, we investigate the relation between the Deddens and spectral radius algebras of two bounded linear operators, noting a similarity between them. Additionally, we char…

Essential norm of composition operators Harmonic Bloch spaces
Y. Estaremi, S. Esmaeili, A. Ebadian
In this paper we characterize essential norm of composition operators on the spaces of Harmonic Bloch functions. These results extends the similar results that were proven for comp…
