Product-type operators from weighted Bergman spaces to Bloch-Orlicz spaces

四川大学学报. 自然科学版, 2020
By constructing some suitable test functions in weighted Bergman space, the boundedness and compactness of the product-type operators from the weighted Bergman space to the Bloch-Orlicz space are characterized in terms of the symbol functions in this ...

Sampling with Derivatives in the Bergman Space [PDF]

Sampling Theory in Signal and Image Processing, 2017
Summary: We characterize sets of sampling for Bergmann space functions and their derivatives. In particular, we show that the methods used in the setting of the Bargmann-Fock space can be adapted to our purpose.

On complex symmetry of composition operators on Bergman space

四川大学学报. 自然科学版, 2020
In this paper, we discuss about the necessary and sufficient conditions for the composition operators on the Bergman space, meanwhile give complex symmetric composition operators on Bergman space whose symbols are linear-fractional but not automorphic.

Kernels of Toeplitz operators on the Bergman space

, 2023
summary:A Coburn theorem says that a nonzero Toeplitz operator on the Hardy space is one-to-one or its adjoint operator is one-to-one.

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

The Zero Product of Toeplitz Operators on the 2-Analytic Weighted Bergman Space

Journal of Function Spaces
Two-analytic weighted Bergman space is a nonanalytic function space which is closely related to analytic functions. In this paper, we mainly discuss the zero product problem for Toeplitz operators on the 2-analytic weighted Bergman space.

On the best mean-square approximation of analytic functions in the Bergman space B₂

Современная математика: Фундаментальные направления
In a Bergman Hilbert space, we study the problem of estimating the best approximation of an analytic function in the unit disk by algebraic polynomials via averaging its modulus of smoothness.

Finite-rank intermediate Hankel operators on the Bergman space

International Journal of Mathematics and Mathematical Sciences, 2001
Let L2=L2(D,r dr dθ/π) be the Lebesgue space on the open unit disc and let La2=L2∩ℋol(D) be the Bergman space. Let P be the orthogonal projection of L2 onto La2 and let Q be the orthogonal projection onto L¯a,02={g∈L2;g¯∈La2,   g(0)=0}. Then I−P≥Q.
