Uniform estimates with data from generalized Lebesgue spaces in periodic structures

open access: yesBoundary Value Problems, 2021
We study various types of uniform Calderón–Zygmund estimates for weak solutions to elliptic equations in periodic homogenization. A global regularity is obtained with respect to the nonhomogeneous term from weighted Lebesgue spaces, Orlicz spaces, and ...

Pointwise multipliers of weighted BMO spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
Let \(w:{\mathbb{R}}\to {\mathbb{R}}^+\) be a weight function satisfying the doubling condition: \(\int_{J}w(x)dx\leq C\int_{I}w(x)dx\), whenever I and J are intervals such that \(I\subset J\) and \(| J| \leq 2| I|\). The paper under review describes the weighted atomic \(H^ 1\)- space \(H_ w^ 1({\mathbb{R}})\) and weighted BMO-space \(BMO_ w({\mathbb ...

Functional Calculus on BMO and Related Spaces

open access: yesJournal of Functional Analysis, 2002
It is considered a nonlinear autonomous superposition operator \[ {\mathbf T}_f [g] = f\circ g \] on a certain subspace \(X\) of the space \(BMO({\mathbb R}^n)\). The question is to characterise those Borel measurable functions \(f\) for which the operator \({\mathbf T}_f\) is continuous or differentiable on \(X\).

A Weighted Variant of Riemann-Liouville Fractional Integrals on ℝn

open access: yesAbstract and Applied Analysis, 2012
We introduce certain type of weighted variant of Riemann-Liouville fractional integral on ℝn and obtain its sharp bounds on the central Morrey and λ-central BMO spaces.

Commutators of Multilinear Calderón-Zygmund Operator on Weighted Herz-Morrey Spaces with Variable Exponents

open access: yesJournal of Function Spaces, 2021
In this paper, we acquire the boundedness of commutators generated by multilinear Calderón-Zygmund operator and BMO functions on products of weighted Herz-Morrey spaces with variable exponents.

$BMO$ Spaces for Laguerre Expansions

open access: yesTaiwanese Journal of Mathematics, 2012
Let $\{\varphi_n^{\alpha}\}_{n \in \mathbb{N}}$ be the Laguerre functions of Hermite type with index $\alpha$. These are eigenfunctions of the Laguerre differential operator $L_\alpha = \dfrac{1}{2}(-\frac{d^2}{dy^2} + y^2 + \frac{1}{y^2}(\alpha^2-\frac{1}{4}))$. We define and study a $BMO$-type space $BMO_{L_{\alpha}}$, which is identified as the dual

Gender Lens Equity Funds: A Methodological Breadth–Accountability Depth Framework and Observed Outcomes

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Despite rapid growth in gender lens investing (GLI), substantial variation remains in how gender lens equity funds (GLEFs) integrate gender equality criteria into investment strategies. We map a universe of 43 GLEFs and develop a framework capturing gender equality screening breadth and accountability depth (fund‐level disclosure and ...

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

The S-Transform on Hardy Spaces and Its Duals

open access: yesInternational Journal of Analysis and Applications, 2015
In this paper, continuity and boundedness results for the continuous S-transform in BMO and Hardy spaces are obtained. Furthermore, the continuous S-transform is also studied on the weighted BMO$_k$ and weighted Hardy spaces associated with a tempered
