WEIGHTED ESTIMATES FOR ROUGH PARAMETRIC MARCINKIEWICZ INTEGRALS [PDF]
Journal of the Korean Mathematical Society, 2007 Summary: We establish a weighted norm inequality for a class of rough parametric Marcinkiewicz integral operators \({\mathcal M}_\Omega^\rho\). As an application of this inequality, we obtain weighted \(L^p\) inequalities for a class of parametric Marcinkiewicz integral operators \({\mathcal M}_{\Omega,\lambda}^{*,\rho}\) and \({\mathcal M}_{\Omega,S}^\

BELTRAMI EQUATIONS REVISITED: MARCINKIEWICZ EXPONENTS AND PAINLEVE-TYPE THEOREM
Проблемы анализа, 2018 We deal with some new results on some types of Beltrami equations. There is a new approach involving the new metric characteristics: the Marcinkiewicz exponents. Another vision is applying the Cauchy-type integral representation to such equations.

Demonstratio Mathematica, 2020 In this article, we study the generalized parabolic parametric Marcinkiewicz integral operators ℳΩ,h,Φ,λ(r){ {\mathcal M} }_{{\Omega },h,{\Phi },\lambda }^{(r)} related to polynomial compound curves.

Evidence Against Syntactic Encapsulation in Large Language Models
Cognitive Science, Volume 50, Issue 3, March 2026.Abstract Transformer‐based large language models (LLMs) have recently demonstrated exceptional performance in a variety of linguistic tasks. LLMs primarily combine information across words in a sentence using the attention mechanism, implemented by “attention heads:” these components assign numerical weights linking different words in the input to one ...

Boundedness of Marcinkiewicz Integrals on RBMO Spaces over Nonhomogeneous Metric Measure Spaces
Journal of Mathematics, 2015 Let X,d,μ be a metric measures space satisfying the upper doubling conditions and the geometrically doubling conditions in the sense of Hytönen. Under the assumption that the dominating function satisfies the weak reverse doubling condition, the authors ...

Journal of Inequalities and Applications, 2020 In this paper, we obtain the existence and boundedness of Marcinkiewicz integrals with homogeneous kernels on central Campanato spaces. Moreover, the existence and boundedness of multilinear Marcinkiewicz integrals on central Campanato spaces are also ...

, 2015 We extend to n-dimensions a characterization of the Marcinkiewicz $L(p,\infty)$ spaces first obtained by Garsia-Rodemich in the one dimensional case. This leads to a new proof of the John-Nirenberg self-improving inequalities.

Beyond Usual Suspects: Revisiting Barriers to Childbearing Decisions in a Low Fertility Setting
Population and Development Review, Volume 52, Issue 1, Page 94-134, March 2026.Abstract Fertility rates in developed countries have declined to historically low levels, yet the reasons remain incompletely understood. This study examines the relative importance of diverse macro contextual constraints on childbearing intentions among young adults (aged 20–35) in Poland, a country emblematic of Europe's fertility decline.
