A Characterization of Vanishing Mean Oscillation

Monatshefte Fur Mathematik, 2006
Let \(\mu\) be a positive, finite Borel measure on the unit circle \(T\). The space of functions of vanishing mean oscillation with respect to \(\mu\) was introduced by \textit{D. Sarason} [Trans. Am. Math. Soc. 207, 391--405 (1975; Zbl 0319.42006)]. \textit{D. S. Jerison} and \textit{C. E.

Functions of Vanishing Mean Oscillation

Mathematische Nachrichten, 1987
Let \(Q_ 0\) represent the unit cube in \({\mathbb{R}}^ n\), let \[ \omega (f,\delta)=\sup_{| h| \leq \delta}\{ \sup_{x,x+h\in Q_ 0}| f(x+h)-f(x)| \} \] represent the essential modulus of continuity of f, and \[ \Omega (f,\delta)=\sup_{diam(Q_ 1\cup Q_ 2)0\), where \(Q_ 1\), \(Q_ 2\) are disjoint subcubes of \(Q_ 0\).

A note on Functions of Vanishing mean Oscillation on the Bidisk

Bulletin of the London Mathematical Society, 1986
For a function \(f\in L^{\infty}(T^ 2)\), T the unit circle, \textit{S.-Y. A. Chang} has proved [Ann. Math., II. Ser. 109, 613-620 (1979; Zbl 0401.28004)] that the Poisson integral \(\Lambda\) is a bounded operator from \(L^ 2(T^ 2)\) to \(L^ 2(d\mu_ f)\), where \[ d\mu_ f= | \nabla_ 1\nabla_ 2 \Lambda f(z_ 1,z_ 2)|^ 2 \log (1/| z_ 1|) \log (1/| z_ 2|)

Spaces of Functions with Bounded and Vanishing Mean Oscillation

2003
We study generalized Campanato spaces and its vanishing subspaces. Our main interest is the connection between the geometry of the domain and the relation of the Campanato spaces to convenient HOlder spaces. We define the vanishing subspace, an analogue of VMO, and study its properties. In particular, we characterize compact subsets of VMO.

Elliptic boundary value problem in Vanishing mean Oscillation hypothesis

1999
The aim of this paper is to prove the well-posedness of the Dirichlet problem \[ \left \{ \begin{aligned} &\mathcal L u+b_iu_{x_i}-(d_ju)_{x_j}+cu=(f_j)_{x_j} \quad \text{for a.e. \(x\in \Omega \)},\\ &u=0\quad \text{on \(\partial \Omega \)}, \end{aligned} \right .
