Two characterizations of central BMO space via the commutators of Hardy operators
, 2021This article addresses two characterizations of BMO(ℝn){\mathrm{BMO}(\mathbb{R}^{n})}-type space via the commutators of Hardy operators with homogeneous kernels on Lebesgue spaces: (i) characterization of the central BMO(ℝn){\mathrm{BMO}(\mathbb{R}^{n})

BMO from dyadic BMO on the bidisc
Journal of the London Mathematical Society, 2008AbstractWe generalize to the bidisc a theorem of Garnett and Jones relating the space BMO of functions of bounded mean oscillation to its martingale counterpart, dyadic BMO. Namely, translation‐averages of suitable families of dyadic BMO functions belong to BMO.

It is known that the compactness of the commutators of point-wise multiplication with bilinear homogeneous Calderon–Zygmund operators acting on product of Lebesgue spaces is characterized by the multiplying function being in the space CMO.

BMO Spaces on Weighted Homogeneous Trees
, 2020We 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 ...

Properties of BMO Functions whose Reciprocals are also BMO
Zeitschrift für Analysis und ihre Anwendungen, 1993The paper gives some properties of the space \(\text{BMO}_ *=\{w\in\text{BMO}: 1/\omega\in\text{BMO}\}\) such as Theorem 1. A real- valued function \(u\) is in \(\text{BMO }\Leftrightarrow\) there exists \(w\in \text{BMO}_ *\) such that \(u=w-1/w\) (a consequence of \(\text{Lip }\alpha\)-operatability on BMO); Theorem 3.

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 |

Applicability of ISNT Rule Using BMO-MRW to Differentiate Between Healthy and Glaucomatous Eyes
Journal of glaucoma, 2018Purpose: 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).
