Noncommutative strong maximals and almost uniform convergence in several directions
Forum of Mathematics, Sigma, 2020 Our first result is a noncommutative form of the Jessen-Marcinkiewicz-Zygmund theorem for the maximal limit of multiparametric martingales or ergodic means.

Primarity of direct sums of Orlicz spaces and Marcinkiewicz spaces [PDF]
Banach Journal of Mathematical Analysis, 2020 Let $\mathbb{Y}$ be either an Orlicz sequence space or a Marcinkiewicz sequence space. We take advantage of the recent advances in the theory of factorization of the identity carried on in [R. Lechner, Subsymmetric weak* Schauder bases and factorization of the identity, arXiv:1804.01372 [math.FA]] to provide conditions on $\mathbb{Y}$ that ensure that,

Journal of Comparative Neurology, Volume 532, Issue 6, June 2024.Graphical Abstract: We used single‐cell transcriptomics to explore cell type and neuronal class diversity, and in situ hybridization chain reaction to view expression in the brain of the nudibranch mollusc, Berghia stephanieae. Gene markers for nudibranch neurons and glia were found.

Journal of Applied Econometrics, Volume 39, Issue 4, Page 620-639, June/July 2024.Summary This paper introduces a novel panel approach to structural vector autoregressive analysis. For identification, we impose independence of structural innovations at the pooled level. We demonstrate robustness of the method under cross‐sectional correlation and heterogeneity through simulation experiments.

Function Spaces with Bounded Lp Means and Their Continuous Functionals
Abstract and Applied Analysis, 2014 This paper studies typical Banach and complete seminormed spaces of locally summable functions and their continuous functionals. Such spaces were introduced long ago as a natural environment to study almost periodic functions (Besicovitch, 1932; Bohr and

Fractional type Marcinkiewicz integrals over non-homogeneous metric measure spaces
Journal of Inequalities and Applications, 2016 The main goal of the paper is to establish the boundedness of the fractional type Marcinkiewicz integral M β , ρ , q $\mathcal{M}_{\beta,\rho,q}$ on non-homogeneous metric measure space which includes the upper doubling and the geometrically doubling ...

Parameter θ-Type Marcinkiewicz Integral on Nonhomogeneous Weighted Generalized Morrey Spaces
Journal of Function Spaces, 2020 Let X,d,μ be a nonhomogeneous metric measure space satisfying the upper doubling and geometrically doubling conditions in the sense of Hytönen. In this setting, the author proves that parameter θ-type Marcinkiewicz integral Mθρ is bounded on the weighted

Magnetic helicity, weak solutions and relaxation of ideal MHD
Communications on Pure and Applied Mathematics, Volume 77, Issue 4, Page 2387-2412, April 2024.Abstract We revisit the issue of conservation of magnetic helicity and the Woltjer‐Taylor relaxation theory in magnetohydrodynamics (MHD) in the context of weak solutions. We introduce a relaxed system for the ideal MHD system, which decouples the effects of hydrodynamic turbulence such as the appearance of a Reynolds stress term from the magnetic ...

Factorization in Fourier restriction theory and near extremizers
Mathematische Nachrichten, Volume 297, Issue 1, Page 195-208, January 2024.Abstract In Fourier restriction theory, abstract so‐called Maurey–Nikishin–Pisier factorization has often been used as a convenient off‐the‐shelf means to prove certain factorizations of the Fourier restriction operator. We give an alternative approach to such factorizations in Fourier restriction theory.

Parabolic Marcinkiewicz integrals on product spaces and extrapolation
Open Mathematics, 2016 In this paper, we study the the parabolic Marcinkiewicz integral MΩ,hρ1,ρ2${\cal M}_{\Omega, h}^{{\rho _{1,}}{\rho _2}}$ on product domains Rn × Rm (n, m ≥ 2). Lp estimates of such operators are obtained under weak conditions on the kernels.
