On the tangent space to the BMO-Teichmüller space

open access: yesJournal of Mathematical Analysis and Applications, 2014
Abstract In a previous paper [31] we established the complex analytic manifold theory of the BMO-Teichmuller space. In this paper we identify the function space which is the tangent space to the BMO-Teichmuller space.

Two characterizations of central BMO space via the commutators of Hardy operators

, 2021
This 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})

Non-commutative BMO space

Archiv der Mathematik, 2000
We consider the non-commutative martingale BMO-version introduced recently by G. Pisier and Q. Xu. Let us denote it by \(BMO(\cal M)\), where \(\cal M\) is \(B(\ell_2)\). We prove that the triangular projection PT (see [1]) is a bounded linear operator from \(B(\ell_2)\) into \(BMO(\cal m)\), obtaining a non-commutative analogue of the well-known fact ...

A revisit to “On BMO and Carleson measures on Riemannian manifolds”

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2023
Let $\mathcal {M}$ be an Ahlfors $n$-regular Riemannian manifold such that either the Ricci curvature is non-negative or the Ricci curvature is bounded from below together with a bound on the gradient of the heat kernel. In the paper [IMRN, 2022, no.

Local-in-Time Solvability and Space Analyticity for the Navier–Stokes Equations with BMO-Type Initial Data

, 2018
It is proved that there exists a local-in-time solution $$u\in C([0,T),bmo({\mathbb {R}}^d)^d)$$ u ∈ C ( [ 0 , T ) , b m o ( R d ) d ) of the Navier–Stokes equations such that every u ( t ) has an analytic extension on a complex domain whose size only ...

Interpolation between noncommutative martingale Hardy and BMO spaces: the case $\textbf {0

Canadian Journal of Mathematics - Journal Canadien de Mathematiques, 2021
Let $\mathcal {M}$ be a semifinite von Nemann algebra equipped with an increasing filtration $(\mathcal {M}_n)_{n\geq 1}$ of (semifinite) von Neumann subalgebras of $\mathcal {M}$ .

BMO and exponential Orlicz space estimates of the discrepancy function in arbitrary dimension

Journal d'Analyse Mathematique, 2014
In the current paper, we obtain discrepancy estimates in exponential Orlicz and BMO spaces in arbitrary dimension d ≥ 3. In particular, we use dyadic harmonic analysis to prove that the dyadic product BMO and exp(L2/(d−1)) norms of the discrepancy ...

On an Equivalent Norm on the Space BMO

Journal of Mathematical Sciences, 2018
We extend the inequality proved by S. V. Bochkarev to a larger class of convolution operators assuming that the Fourier transforms of the kernels of these operators satisfy certain conditions in the spirit of the Hormander–Mikhlin multiplier theorem. Therefore, we give a new characterization of BMO.

On compactness of commutators of multiplication and bilinear pseudodifferential operators and a new subspace of BMO

, 2020
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.
