Fredholm multiplication operators on Banach spaces of analytic functions on the open unit disk
Paul Bourdon, Mahsa Fatehi
We identify properties of a Banach space of analytic functions on the open unit disk in the complex plane ensuring that a multiplication operator $M_ψ: \…
Products of composition and differentiation operators on the Hardy space
Mahbube Moradi, Mahsa Fatehi
We consider the products of composition and differentiation operators on the Hardy space. We provide a complete characterization of the boundedness and compactness of these operato…
Weighted Composition--Differentiation Operator on the Hardy and Weighted Bergman Spaces
Mahsa Fatehi
In this paper, we consider the sum of weighted composition operator and the weighted composition--differentiation operator on the Hardy and we…
Complex symmetric Weighted Composition--Differentiation Operators of order on the Weighted Bergman Spaces
Mahbube Moradi, Mahsa Fatehi
We study the complex symmetric structure of weighted composition--differentiation operators of order on the weighted Bergman spaces with respect to some conjugations.…
Numerical range of weighted composition operators which contain zero
Mahsa Fatehi, Asma Negahdari
In this paper, we study when zero belongs to the numerical range of weighted composition operators on the Fock space , where , $a,b \in \mathb…
Weighted composition operators on the Fock space
Mahsa Fatehi
In this paper, we study weighted composition operators on the Fock space. We show that a weighted composition operator is cohyponorma if and only if it is normal. Moreover, we give…
Complex symmetric weighted composition operators
Mahsa Fatehi
In this paper we find all complex symmetric weighted composition operators with special conjugations. Then we give spectral properties of these complex symmetric weighted compositi…
Quasinormal and hyponormal weighted composition operators on and with linear fractional compositional symbol
Mahsa Fatehi, Mahmood Haji Shaabani, Derek Thompson
In this paper, we study quasinormal and hyponormal composition operators \W with linear fractional compositional symbol $\ph$ on the Hardy and weighted Bergman spaces. We character…
Normal, cohyponormal and normaloid weighted composition operators on the Hardy and weighted Bergman spaces
Mahsa Fatehi, Mahmood Haji Shaabani
If is analytic on the open unit disk and is an analytic self-map of , the weighted composition operator is defined by $C_{ψ,φ}f(z)=ψ(z)f…
Which weighted composition operators are hyponormal on the Hardy and weighted Bergman spaces?
Mahsa Fatehi, Mahmood Haji Shaabani
In this paper, we study hyponormal weighed composition operators on the Hardy and weighted Bergman spaces. For functions which are not the zero function, we ch…
