Upper and Lower Bounds for Essential Norm of Weighted Composition Operators from Bergman Spaces with Békollé Weights

open access: yesJournal of Function Spaces, 2020
Let σ be a weight function such that σ/1−z2α is in the class Bp0α of Békollé weights, μ a normal weight function, ψ a holomorphic map on D, and φ a holomorphic self-map on D.

Volterra composition operators between weighted Bergman spaces and weighted Bloch type spaces [PDF]

open access: yes, 2010

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

open access: yesJournal 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 ...

Weighted Sub-Bergman Hilbert spaces in the unit ball of ℂn

open access: yesConcrete Operators, 2020
In this note, we study defect operators in the case of holomorphic functions of the unit ball of ℂn. These operators are built from weighted Bergman kernel with a holomorphic vector.

Weighted reproducing kernels in Bergman spaces.

open access: yesMichigan Mathematical Journal, 1994
A major inspiration for this paper is the factorization theory developed by \textit{H. Hedenmalm} [J. Reine Angew. Math. 422, 45-68 (1991; Zbl 0734.30040)] for the standard Bergman space \(A^2\), and later generalized to the Bergman space \(A^2\) by \textit{P. Duren}, \textit{D. Khavinson}, \textit{H. S. Shapiro} and \textit{C. Sundberg} [Pac. J. Math.

On weights which admit the reproducing kernel of Bergman type

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
In this paper we consider (1) the weights of integration for which the reproducing kernel of the Bergman type can be defined, i.e., the admissible weights, and (2) the kernels defined by such weights.
