Multiplicative Isometries and Isometric Zero-Divisors
- MathematicsCanadian Journal of Mathematics
- 2010
Abstract For some Banach spaces of analytic functions in the unit disk (weighted Bergman spaces, Bloch space, Dirichlet-type spaces), the isometric pointwise multipliers are found to be unimodular…
Mean Ergodicity of Multiplication Operators on the Bloch and Besov Spaces
- Mathematics
- 2020
In this paper, the power boundedness and mean ergodicity of multiplication operators are investigated on the Bloch space $\mathcal{B}$, the little Bloch space $\mathcal{B }_0 $ and the Besov Space…
Weighted composition operators on the Bloch space
- MathematicsBulletin of the Australian Mathematical Society
- 2001
We characterise bounded and compact weighted composition operators on the Bloch space and the little Bloch space. The results generalise the known corresponding results on composition operators and…
Holomorphic semigroups and Sarason’s characterization of vanishing mean oscillation
- Mathematics
- 2022
It is a classical theorem of Sarason that an analytic function of bounded mean oscillation (BMOA), is of vanishing mean oscillation if and only if its rotations converge in norm to the original…
Closure in the Logarithmic Bloch Norm of Dirichlet Type Spaces
- Mathematics, Computer Science
- 2021
This paper characterize the closure of Dirichlet type space with respect to logarithmic Bloch space, and revisits a description of the boundedness of composition operator.
Invertible and isometric weighted composition operators
- Mathematics
- 2021
We consider abstract Banach spaces of analytic functions on general bounded domains that satisfy only a minimum number of axioms. We describe all invertible (equivalently, surjective) weighted…
On model spaces and density of functions regular on the boundary
- Mathematics
- 2021
We characterize the model spaces KΘ in which functions with smooth boundary extensions are dense. It turns out that such approximation is possible if and only if the singular measure associated to…

We characterize the model spaces KΘ in which functions with smooth boundary extensions are dense. It is shown that such approximations are possible if and only if the singular measure associated to…
Products of Unbounded Bloch Functions
- MathematicsOperator Theory, Functional Analysis and Applications
- 2021
We give new constructions of pair of functions (f, g), analytic in the unit disc, with g ∈ H∞ and f an unbounded Bloch function, such that the product g ⋅ f is not a Bloch function.
MULTIPLIERS OF DIRICHLET-TYPE SUBSPACES OF BLOCH SPACE
- Mathematics
- 2020
Let M(X,Y ) denote the space of multipliers from X to Y, where X and Y are analytic function spaces. As we known, for Dirichlettype spaces D α, M(D p−1,D q q−1) = {0}, if p 6= q, 0 < p, q < ∞. If 0 <…
