On a Local Mean Oscillation Decomposition
Jonathan Poelhuis, Alberto Torchinsky
In this note we generate two local median oscillation decompositions of an arbitrary measurable function and discuss some applications to Calderón-Zygmund singular integral operato…

Medians, Continuity, and Oscillation
Jonathan Poelhuis, Alberto Torchinsky
In this paper we consider properties of medians as they pertain to the continuity and vanishing oscillation of a function. Our approach is based on the observation that medians are…

Characterizations of the Hardy Space and BMO
Wael Abu-Shammala, Ji-Liang Shiu, Alberto Torchinsky
We describe the spaces and BMO in terms of their closely related, simpler dyadic and two-sided counterparts. As a result of these characterizations we establish when…
