From Populism to Fascism? On Our Present‐Time Political Categories

open access: yesSociology 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?

The Berezin transform and operators on spaces of analytic functions [PDF]

open access: yes, 1997
In this article we will illustrate how the Berezin transform (or symbol) can be used to study classes of operators on certain spaces of analytic functions, such as the Hardy space, the Bergman space and the Fock space.

Semiclassical inequalities for Dirichlet and Neumann Laplacians on convex domains

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 762-822, March 2026.
Abstract We are interested in inequalities that bound the Riesz means of the eigenvalues of the Dirichlet and Neumann Laplacians in terms of their semiclassical counterpart. We show that the classical inequalities of Berezin–Li–Yau and Kröger, valid for Riesz exponents γ≥1$\gamma \ge 1$, extend to certain values γ<1$\gamma <1$, provided the underlying ...

Covariant derivatives of the Berezin transform

open access: yes, 2011
Improving upon recent results of Coburn, Xia, Li, Engliš and Zhang, Bommier-Hato, and others, we give estimates for higher-order covariant derivatives of the Berezin transform of bounded linear operators on a reproducing kernel Hilbert space of ...

Iterates of a Berezin-type transform [PDF]

open access: yes, 2006
Let B be the open unit ball of Rn and dV denote the Lebesgue measure on Rn normalized so that the measure of B equals 1. Suppose f∈L1(B,dV). The Berezin-type transform of f is defined byBf(x)=∫Bf(y)(1−|x|2)2(1−2x⋅y+|x|2|y|2)n/2+1dV(y),x∈B.

Quantitative Mapping of Fibrotic Tissue Mechanics via Brillouin Spectroscopy

open access: yesJournal of Biophotonics, Volume 19, Issue 3, March 2026.
Brillouin spectroscopy distinguishes fibrotic from healthy tissue based on localized stiffness changes and enables real‐time monitoring of dynamic alterations in viscoelastic properties during fibrogenesis.ABSTRACTFibrosis is a pathological scarring process that disrupts tissue architecture, and is characterized by excessive extracellular matrix (ECM ...

Participation Beyond Compliance: Who Tried to Influence Other People's Vaccination Behaviour During the COVID‐19 Crisis?

open access: yesSociology 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 ...

A sufficient condition for $L^p$ regularity of the Berezin transform

open access: yes, 2022
We prove that the Berezin transform is $L^p$ regular on a large class of domains in $\mathbb{C}^n$ and not $L^2$ regular on the Hartogs triangle.A major revision. To appear in Complex Var.

Berezin number and Berezin norm inequalities for operator matrices [PDF]

open access: yes, 2023
We establish new upper bounds for Berezin number and Berezin norm of operator matrices, which are refinements of the existing bounds. Among other bounds, we prove that if $A=[A_{ij}]$ is an $n\times n$ operator matrix with $A_{ij}\in\mathbb{B}(\mathcal{H}
