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.

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.

BMO estimates for the -Laplacian
Nonlinear Analysis: Theory, Methods & Applications, 2012The authors prove BMO estimates of the inhomogeneous \(p\)-Laplace system \[ -\text{div }(|\nabla u|^{p-2}\nabla u)=\text{div }f,\qquad p\in(1,\infty). \] It is shown that \(f\in\) BMO implies \(|\nabla u|^{p-2}\nabla u\in\) BMO, which is the limiting case of the nonlinear Calderón-Zygmund theory.

Let \(B\) denote the unit ball in \(\mathbb{C}^n\), \(n \geq 1\), and \(m\) the \(2n\)-dimensional Lebesgue measure on \(B\) normalized by \(m(B) = 1\), and \(\sigma\) is the normalized surface measure on its boundary \(\partial B\). The main result is: Theorem. Let \(f \in L^2 (\sigma)\) and \(F = P[f]\) denotes Poisson- Szegö integral.

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 \(z^ + = \max (z,0)\).
