Positive Toeplitz operators between doubling Fock spaces
四川大学学报. 自然科学版, 2020 In this paper, we characterize the boundedness and compactness of the Toeplitz operator between doubling Fock spaces in terms of averaging functions and t-Berezin transform.

Compact Operators on the Bergman Spaces with Variable Exponents on the Unit Disc of C
International Journal of Mathematics and Mathematical Sciences, 2018 We study the compactness of some classes of bounded operators on the Bergman space with variable exponent. We show that via extrapolation, some results on boundedness of the Toeplitz operators with general L1 symbols and compactness of bounded operators ...

Journal of Sleep Research, Volume 35, Issue 5, October 2026.ABSTRACT Emerging evidence links COVID‐19 to the predisposition of Parkinson's disease (PD). However, the relationship between long COVID and prodromal PD‐like features remains unclear, particularly in long COVID participants with dream‐enactment behaviours (DEBs) that may be suggestive of possible REM sleep behaviour disorder.

On the closed range problem for composition operators on the Dirichlet space
Concrete Operators, 2019 We characterize closed range composition operators on the Dirichlet space for a particular class of composition symbols. The characterization relies on a result about Fredholm Toeplitz operators with BMO1 symbols, and with Berezin transforms of vanishing

Affective regimes and ontological security: When empathy threatens the state
Political Psychology, Volume 47, Issue 5, October 2026.Abstract The ontological security of states may be threatened by the politics of empathy. Empathy—as a contested affective‐political field—has a capacity to both consolidate and unravel dominant understandings of identity, security, political subjectivity, and self‐other relations.

Hyperbolic harmonic functions and the associated integral equations
Annals of the West University of Timisoara: Mathematics and Computer Science, 2015 In this paper we consider a class of integral equations associated with the invariant mean value property of hyperbolic harmonic functions. We have shown that nonconstant solutions of these integral equations are functions of unbounded variations and do ...

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.Abstract We describe and discuss two finds of large and untypical belemnite rostra originating from the upper part of the Sundance Formation (Oxfordian) of Wyoming, USA. With a diameter reaching c. 60 mm at the anterior end, these rostra are the thickest known for belemnites so far.

Reconfiguring Gendered Power in Families Through Men's Emotions
Journal of Family Theory &Review, Volume 18, Issue 2, Page 317-327, June 2026.ABSTRACT This article calls for a fundamental theoretical shift from masculinity to men as embodied, emotional, and reflexive agents. Such a shift makes gendered power visible as men enact, reproduce, and at times unsettle gendered power within families, addressing the persistent theoretical challenge about how masculinities are discussed.

Berezin transform in polynomial Bergman spaces
, 2010 Fix a smooth weight function Q in the plane, subject to a growth condition from below. Let K_(m,n) denote the reproducing kernel for the Hilbert space of analytic polynomials of degree at most n - 1 of finite L^2-norm with respect to the measure e^(-mQ ...
