Essential Norms of Stević–Sharma Operators from General Banach Spaces into Zygmund-Type Spaces

Journal of Mathematics, 2022
A Stević–Sharma operator denoted by Tψ1,ψ2,φ is a generalization product of multiplication, differentiation, and composition operators. Using several restrictive terms, we characterize an approximation of the essential norm of the Stević–Sharma operator ...

Volterra composition operators from generalized weighted weighted Bergman spaces to µ-Bloch spaces

Journal of Function Spaces and Applications, 2009
Let φ be a holomorphic self-map and g be a fixed holomorphic function on the unit ball B. The boundedness and compactness of the operator Tg,φf(z)=∫01f(φ(tz))ℜg(tz)dtt from the generalized weighted Bergman space into the µ-Bloch space are studied in this

Toeplitz operators on weighted harmonic Bergman spaces [PDF]

Banach Journal of Mathematical Analysis, 2018
In this paper, we study Toeplitz operators on the weighted harmonic Bergman spaces with nonnegative symbols, the weights we choose here are Muckenhoupt A_2 weights. Results obtained include characterizations of bounded Toeplitz operators, compact Toeplitz operators, invertible Toeplitz operators and Toeplitz operators in the Schatten classes.

SOME INEQUALITIES BETWEEN THE BEST SIMULTANEOUS APPROXIMATION AND MODULUS OF CONTINUITY IN THE WEIGHTED BERGMAN SPACE

Ural Mathematical Journal, 2023
Some inequalities between the best simultaneous approximation of functions and their intermediate derivatives, and the modulus of continuity in a weighted Bergman space are obtained. When the weight function is \(\gamma(\rho)=\rho^\alpha,\) \(\alpha>0\),

Composition operators on weighted Bergman-Orlicz spaces [PDF]

Bulletin of the Australian Mathematical Society, 2007
In this paper, composition operators acting on Bergman-Orlicz spaces are studied, where ψ is a non-constant, non-decreasing convex function defined on (-∞, ∞) which satisfies the growth condition . In fact, under a mild condition on ∞, we show that every holomorphic-self map ∞ of induces a bounded composition operator on and C∞ is compact on if and ...

Boundedness and Compactness of Weighted Composition Operators From Banach Spaces of Holomorphic Functions to Weighted-Type Banach Spaces on the Polydisk

Journal of Function Spaces
In this work, we characterize the bounded and compact weighted composition operators from a large class of Banach space X of holomorphic functions on the open unit polydisk Dn into weighted-type Banach spaces of holomorphic functions on Dn.

WEIGHTED HARMONIC BERGMAN FUNCTIONS ON HALF-SPACES [PDF]

Journal of the Korean Mathematical Society, 2005
Given a positive integer \(n\), let \({\mathbb H}={\mathbb R}^{n-1}\times {\mathbb R}_+\) be the upper half-space where \({\mathbb R}_+\) denotes the set of all positive real numbers.
