BMO Boundedness for Banach Space Valued Singular Integrals

Analysis in Theory and Applications, 2011
Summary: We consider a class of Banach space valued singular integrals. The \(L^p\) boundedness of these operators is obtained. The paper discusses their boundedness from BMO to BMO. As applications, we get BMO boundedness for the classic \(g\)-function and the Marcinkiewicz integral. Some known results are improved.

Interpolation inequalities between Lorentz space and BMO: the endpoint case \((L^{1,\infty}, BMO)\)

Electronic Journal of Differential Equations, 2019
Summary: We prove interpolation inequalities by means of the Lorentz norm, BMO norm, and the fractional Sobolev norm. In particular, we obtain an interpolation inequality for \((L^{1,\infty}, BMO)\), that we call the endpoint case.

Weighted estimates for fractional bilinear Hardy operators on variable exponent Morrey–Herz space

Journal of Inequalities and Applications
In this article, we analyze the boundedness for the fractional bilinear Hardy operators on variable exponent weighted Morrey–Herz spaces M K ˙ q , p ( ⋅ ) α ( ⋅ ) , λ ( w ) ${M\dot{K}^{\alpha (\cdot ),\lambda}_{q,p(\cdot)}(w)}$ .

The multilinear commutators of Hardy operator on variable central Morrey spaces(变指数中心Morrey空间的多线性Hardy算子交换子)

Zhejiang Daxue xuebao. Lixue ban
With the help of the boundedness of the n-dimensional fractional Hardy operator and its adjoint operator on Lebesgue space with variable exponent, by applying hierarchical decomposition of function and real variable techniques, we obtain the boundedness ...

Function spaces of BMO and Campanato type

Electronic Journal of Differential Equations, 2002
To obtain the Littlewood-Paley characterization for Campanato spaces $mathcal{L}^{2,lambda}$ modulo polynomials (which contain as special case the John and Nirenberg space $BMO$), we define and study a scale of function spaces on $mathbb{R}^{n}$.

$\mathit{BMO}$ spaces for nondoubling metric measure spaces

, 2020
In this article we study the family of $\mathit{BMO}^p$ spaces, $p \geq 1$, in the general context of metric measure spaces. We give a characterization theorem that allows to describe all possible relations between these spaces considered as sets of functions.

Bounded oscillation operators on BMO spaces

Mathematische Zeitschrift
Bounded Oscillation (BO) operators were recently introduced in the author's paper [13], where it was proved that many operators in harmonic analysis (Calderón-Zygmund operators, Carleson type operators, martingale transforms, Littlewood-Paley square functions, maximal operators, etc) are $BO$ operators.
