A-Davis-Wielandt-Berezin radius inequalities
Communications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2023 We consider operator $V$ on the reproducing kernel Hilbert space $\mathcal{H}=\mathcal{H}(\Omega)$ over some set $\Omega$ with the reproducing kernel $K_{\mathcal{H},\lambda}(z)=K(z,\lambda)$ and define A-Davis-Wielandt-Berezin radius $\eta_{A}(V)$ by ...

REVERSE INEQUALITIES FOR THE BEREZIN NUMBER OF OPERATORS [PDF]
Proceedings of the Institute of Mathematics and Mechanics,National Academy of Sciences of Azerbaijan, 2021 For a bounded linear operator A on a reproducing kernel Hilbert space H (Ω), with normalized reproducing kernel b k λ = k λ k k λ k , the Berezin symbol, Berezin number and Berezin norm are defined respectively by e A ( λ ) = h A b k λ , b k λ i , ber ( A

Applications of Alughte Transform for Berezin Radius Inequalities
International Conference on Pioneer and Innovative Studies, 2023 – In functional analysis, linear operators induced by functions are frequently encountered; thesecontain Hankel operators, constitution operators, and Toeplitz operators. The symbol of the resultantoperator is another name for the inciting function.

Berezin number inequalities via convex functions
Filomat, 2022 The Berezin symbol ?A of an operator A on the reproducing kernel Hilbert space H (?) over some set ? with the reproducing kernel k? is defined by ? (?) = ?A k?/||k?||, k?/||k?||?, ? ? ?. The Berezin number of an operator A is defined by ber(A) := sup ?

New estimations for the Berezin number inequality
Journal of Inequalities and Applications, 2020 In this paper, by the definition of Berezin number, we present some inequalities involving the operator geometric mean. For instance, it is shown that if X , Y , Z ∈ L ( H ) $X, Y, Z\in {\mathcal{L}}(\mathcal{H})$ such that X and Y are positive operators,

The nation in bronze and granite: Creating national monuments in post‐Soviet Bishkek
Nations and Nationalism, Volume 29, Issue 2, Page 648-668, April 2023., 2023 Abstract Scholars of nationalism have long looked to material forms of symbolic power to understand the politics and cultures of nations, and national monuments specifically have been studied as reflections of ideological programmes of political regimes. However, these approaches have paid insufficient attention to processes of creation.

Multiplication Operator with BMO Symbols and Berezin Transform [PDF]
Journal of Function Spaces, 2015 We discuss multiplication operator with a special symbol on the weighted Bergman space of the unit ball. We give the necessary and sufficient conditions for the compactness of multiplication operator on the weighted Bergman space of the unit ball.
