BMO and the John-Nirenberg Inequality on Measure Spaces

Analysis and Geometry in Metric Spaces, 2020
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.

Advection Dispersion Equation and BMO Space

Journal of Applied Mathematics and Physics, 2013
In this paper, we provide a new way of characterizing the upper and lower bound for the concentration and the gradient of concentration in advection dispersion equation under the condition that source term, concentration and stirring term belong to BMO space.

Littlewood-Paley Operators on Morrey Spaces with Variable Exponent

The Scientific World Journal, 2014
By applying the vector-valued inequalities for the Littlewood-Paley operators and their commutators on Lebesgue spaces with variable exponent, the boundedness of the Littlewood-Paley operators, including the Lusin area integrals, the Littlewood-Paley g ...

BMO on Weighted Bergman Spaces Over Tubular Domains

Complex Analysis and Operator Theory
In this paper, we characterize Bounded Mean Oscillation (BMO) and establish their connection with Hankel operators on weighted Bergman spaces over tubular domains. By utilizing the space BMO, we provide a new characterization of Bloch spaces on tubular domains. Next, we define a modified projection operator and prove its boundedness.

BMO from dyadic BMO via expectations on product spaces of homogeneous type

Journal of Functional Analysis, 2013
Based on quotations from the authors' abstract: In this paper, by ``using the random dyadic lattices developed by \textit{T. Hytönen} and \textit{A. Kairema}'' [Colloq. Math. 126, No. 1, 1--33 (2012; Zbl 1244.42010)], the authors set up ``a bridge between BMO and dyadic BMO, and hence one between VMO and dyadic VMO, via expectations over dyadic ...
