Berezin transform and Toeplitz operators on polygonal domains
Complex Variables and Elliptic Equations, 2021 We consider reflexive Bergman spaces on polygonal domains Ω of the complex plane. With some restrictions to the angles of the boundary of Ω, we show that the boundedness of the Toeplitz operator with a positive symbol g is equivalent to the boundedness ...

On some numerical characteristics of operators
Arab Journal of Mathematical Sciences, 2015 We investigate some numerical characteristics of Toeplitz operators including the numerical range, maximal numerical range and maximal Berezin set. Further, we establish an inequality for the Berezin number of an arbitrary operator on the Hardy–Hilbert ...

Toeplitz Operators on the Bergman Space of Planar Domains with Essentially Radial Symbols
International Journal of Mathematics and Mathematical Sciences, 2011 We study the problem of the boundedness and compactness of 𝑇𝜙 when 𝜙∈𝐿2(Ω) and Ω is a planar domain. We find a necessary and sufficient condition while imposing a condition that generalizes the notion of radial symbol on the disk.

Boundary behavior of Berezin symbols and related results
Filomat, 2019 For a given function ? ? H? with |?(z)| < 1 (z ? D), we associate some special operators subspace and study some properties of these operators including behavior of their Berezin symbols. It turns that such boundary behavior is closely related to the Blaschke condition of sequences in the unit disk D of the complex plane.

On the weak limit of compact operators on the reproducing kernel Hilbert space and related questions
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016 By applying the so-called Berezin symbols method we prove a Gohberg- Krein type theorem on the weak limit of compact operators on the non- standard reproducing kernel Hilbert space which essentially improves the similar results of Karaev [5]: We also in ...

From Populism to Fascism? On Our Present‐Time Political Categories
Sociology Lens, Volume 39, Issue 2, Page 240-248, June 2026.ABSTRACT With the global rise of far‐right governments, two categories are available to describe this aspect of our current times: populism and fascism. This raises a twofold question: analytically, which is the most accurate to describe these authoritarian governments?

A Method for Weight Multiplicity Computation Based on Berezin Quantization
Symmetry, Integrability and Geometry: Methods and Applications, 2009 Let G be a compact semisimple Lie group and T be a maximal torus of G. We describe a method for weight multiplicity computation in unitary irreducible representations of G, based on the theory of Berezin quantization on G/T.

Berezin-toeplitz quantization and complex weyl quantization of the torus t${}^2$ [PDF]
, 2017 In this paper, we give a correspondence between the Berezin-Toeplitz and the complex Weyl quantizations of the torus $ \mathbb{T}^2$. To achieve this, we use the correspondence between the Berezin-Toeplitz and the complex Weyl quantizations of the ...

Sociology of Health &Illness, Volume 48, Issue 3, March 2026.ABSTRACT In this paper, we call for more attention to be paid to what we call ordinary contributions to public health policies: the propensity of ordinary citizens to actively influence others to follow or reject a health policy. Shifting the focus from personal compliance to active participation (i.e., ordinary contribution) raises distinct questions ...
