BMO Spaces on Weighted Homogeneous Trees

, 2020
We consider an infinite homogeneous tree $${\mathcal {V}}$$ V endowed with the usual metric d defined on graphs and a weighted measure $$\mu $$ μ . The metric measure space $$({\mathcal {V}},d,\mu )$$ ( V , d , μ ) is nondoubling and of exponential ...

One-Sided BMO Spaces

Journal of the London Mathematical Society, 1994
In this paper we introduce the one-sided sharp functions defined by \[ f_ +^ \# (x) = \sup_{h > 0} {1 \over h} \int^{x + h}_ x \left( f(y) - {1 \over h} \int^{x + 2h}_{x + h} f \right)^ + dy \] and \[ f_ -^ \# (x) = \sup_{h > 0} {1 \over h} \int^ x_{x - h} \left( f(y) - {1 \over h} \int^{x - h}_{x-2h} f \right)^ + dy \] where \(z^ + = \max (z,0)\).

Boundedness results for commutators with BMO functions via weighted estimates: a comprehensive approach

Mathematische Annalen, 2017
We present a unified method to obtain unweighted and weighted estimates of linear and multilinear commutators with BMO functions, that is amenable to a plethora of operators and functional settings.

John–Nirenberg Inequalities and Weight Invariant BMO Spaces

Journal of Geometric Analysis, 2017

A note on generalized Fujii-Wilson conditions and BMO spaces

Israel Journal of Mathematics, 2019
In this note we generalize the definition of the Fujii-Wilson condition providing quantitative characterizations of some interesting classes of weights, such as A ∞ , A ∞ weak and C p , in terms of BMO type spaces suited to them.

Applicability of ISNT Rule Using BMO-MRW to Differentiate Between Healthy and Glaucomatous Eyes

Journal of glaucoma, 2018
Purpose: We evaluated the applicability of the ISNT rule using Bruch’s membrane opening minimum rim width (BMO-MRW) in healthy eyes and eyes with normal tension glaucoma (NTG).

A characterization of BMO in terms of endpoint bounds for commutators of singular integrals

Israel Journal of Mathematics, 2018
We provide a characterization of BMO in terms of endpoint boundedness of commutators of singular integrals. In particular, in one dimension, we show that ∥b∥BMO ≃ B, where B is the best constant in the endpoint L log L modular estimate for the commutator

Variational inequalities for the commutators of rough operators with BMO functions

Science China Mathematics, 2017
Starting with the relatively simple observation that the variational estimates of the commutators of the standard Calderón-Zygmund operators with the bounded mean oscillation (BMO) functions can be obtained from their weighted variational estimates, we ...

BMO-quasiconformal mappings

Journal d'Analyse Mathématique, 2001
Let \(f\) denote an ACL sense-preserving open and discrete mapping defined in a domain of the complex plane (where ACL stands for absolutely continuous on lines). Then the complex dilatation \(\mu(z)=\overline \partial f(z)/ \partial f(z)\) with \(|\mu |
