BMO with respect to Banach function spaces

open access: greenMathematische 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} \|_ ...

$BMO$ spaces for nondoubling metric measure spaces [PDF]

open access: greenPublicacions 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

open access: bronzeJournal 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

open access: bronzeRevista 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]

open access: greenMathematische 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]

open access: yesActa 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

open access: greenComplex 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.

Products of Functions in Hardy and Lipschitz or BMO Spaces [PDF]

open access: green, 2009
We define as a distribution the product of a function (or distribution) h in some Hardy space Hp with a function b in the dual space of Hp. Moreover, we prove that the product bxh may be written as the sum of an integrable function with a distribution that belongs to some Hardy-Orlicz space, or to the same Hardy space Hp, depending on the values of p.

Universal Teichmüller space and BMO

open access: yesAdvances in Mathematics, 2013
AbstractWe first give some new characterizations on BMOA–Teichmüller space and various characterizations on VMOA–Teichmüller space as well. In particular, we prove that a quasisymmetric conformal welding h corresponds to an asymptotically smooth curve in the sense of Pommerenke (1978) [32] precisely when h is absolutely continuous with logh′∈VMO.
