Composition Operator on Bergman-Orlicz Space

open access: yesJournal of Inequalities and Applications, 2009
Let denote the open unit disk in the complex plane and let denote the normalized area measure on . For and a twice differentiable, nonconstant, nondecreasing, nonnegative, and convex function on , the Bergman-Orlicz space is defined as ...

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

open access: yes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 ...

Fourier representations in Bergman spaces

open access: yesJournal of Mathematical Analysis and Applications, 2019
We consider a class of domains, generalizing the upper half-plane, and admitting rotational, translational and scaling symmetries, analogous to the half-plane. We prove Paley-Wiener type representations of functions in Bergman spaces of such domains with respect to each of these three groups of symmetries.

On complex symmetry of composition operators on Bergman space

open access: yes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.

Finite-rank intermediate Hankel operators on the Bergman space

open access: yesInternational 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.

Sarason Conjecture on the Bergman Space [PDF]

open access: yesInternational Mathematics Research Notices, 2016
We provide a counterexample to the Sarason Conjecture for the Bergman space and present a characterisation of bounded Toeplitz products on the Bergman space in terms of test functions by means of a dyadic model approach. We also present some results about two-weighted estimates for the Bergman projection.

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced 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

open access: yesJournal 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.
