BMO with respect to Banach function spaces
Mathematische Annalen, 2022 For every cube $Q \subset \mathbb{R}^n$ we let $X_Q$ be a quasi-Banach function space over $Q$ such that $\|\chi_Q\|_{X_Q} \simeq 1$, and for $X= \{X_Q\}$ define \begin{align*} \|f\|_{\mathrm{BMO}_X}&:=\sup_Q \,\|f-{\textstyle\frac{1}{|Q|}\int_Qf} \|_ ...

A Characterization of Central BMO Space via the Commutator of Fractional Hardy Operator
Journal of Function Spaces, 2020 This paper is devoted in characterizing the central BMO ℝn space via the commutator of the fractional Hardy operator with rough kernel. Precisely, by a more explicit decomposition of the operator and the kernel function, we will show that if the symbol ...

$BMO$ spaces for nondoubling metric measure spaces [PDF]
Publicacions Matemàtiques, 2020 In this article we study the family of $BMO^p$ 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.

Functional Calculus on BMO and Related Spaces
Journal 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 \(X\).

Comparison of the classical BMO with the BMO spaces associated with operators and applications
Revista Matemática Iberoamericana, 2008 Let L be a generator of a semigroup satisfying the Gaussian upper bounds. A new {\rm BMO}_L space associated with L was recently introduced in [Duong, X. T.

BMO spaces associated with semigroups of operators [PDF]
Mathematische Annalen, 2011 We study BMO spaces associated with semigroup of operators and apply the results to boundedness of Fourier multipliers. We prove a universal interpolation theorem for BMO spaces and prove the boundedness of a class of Fourier multipliers on noncommutative Lp spaces for all 1 < p < \infty, with optimal constants in p.

Characterizations of Weighted BMO Space and Its Application [PDF]
Acta Mathematica Sinica, English Series, 2017 In this paper, we prove that the weighted BMO space BMOp(ω)={f∈Lloc1:supQ‖χQ‖Lp(ω)−1‖(f−fQ)ω−1χQ‖Lp(ω)

BMO and Hankel Operators on Bergman Space of the Siegel Upper Half-Space
Complex Analysis and Operator Theory, 2021 On the setting of the Siegel upper half-space we study the spaces of bounded and vanishing mean oscillations which are defined in terms of the Berezin transform, we use them to characterize bounded and compact Hankel operators on Bergman space.

Magnetic anomaly inversion through the novel barnacles mating optimization algorithm [PDF]
Scientific Reports, 2022 Dealing with the ill-posed and non-unique nature of the non-linear geophysical inverse problem via local optimizers requires the use of some regularization methods, constraints, and prior information about the Earth's complex interior. Another difficulty
