BMO and the John-Nirenberg Inequality on Measure Spaces [PDF]
We study the space BMO𝒢 (𝕏) in the general setting of a measure space 𝕏 with a fixed collection 𝒢 of measurable sets of positive and finite measure, consisting of functions of bounded mean oscillation on sets in 𝒢.

Universal Teichmüller space and BMO
AbstractWe first give some new characterizations on BMOA–Teichmüller space and various characterizations on VMOA–Teichmüller space as well. In particular, we prove that a quasisymmetric conformal welding h corresponds to an asymptotically smooth curve in the sense of Pommerenke (1978) [32] precisely when h is absolutely continuous with logh′∈VMO.

Products of Functions in Hardy and Lipschitz or BMO Spaces [PDF]
We define as a distribution the product of a function (or distribution) h in some Hardy space Hp with a function b in the dual space of Hp. Moreover, we prove that the product bxh may be written as the sum of an integrable function with a distribution that belongs to some Hardy-Orlicz space, or to the same Hardy space Hp, depending on the values of p.

A note on the BMO-Teichmüller space
Abstract Astala–Zinsmeister [2] introduced a new topology on the set of all strongly quasisymmetric homeomorphisms of the unit circle denoted by SQS ( S 1 ) by means of BMO norm. Under this new topology, we prove that SQS ( S 1 ) is a partial topological group, and the characteristic topological subgroup of ...

On the tangent space to the BMO-Teichmüller space
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.

In this paper, we study the boundedness of the commutator of the rough fractional Hausdorff operator on grand-variable-Herz-Morrey spaces when the symbol functions belong to bounded mean oscillations (BMO) space.

A characterization of $${{\mathrm{BMO}}}$$BMO self-maps of a metric measure space [PDF]
This paper studies functions of bounded mean oscillation ($${{\mathrm{BMO}}}$$BMO) on metric spaces equipped with a doubling measure. The main result gives characterizations for mappings that preserve $${{\mathrm{BMO}}}$$BMO.

Our goal is to obtain the John–Nirenberg inequality for ball Banach function spaces X, provided that the Hardy–Littlewood maximal operator M is bounded on the associate space X′ $X'$ by using the extrapolation.
