John–Nirenberg Inequalities for Noncommutative Column BMO and Lipschitz Martingales

open access: yesCommunications in Mathematical Physics
In this paper, we continue the study of John-Nirenberg theorems for BMO/Lipschitz spaces in the noncommutative martingale setting. As conjectured from the classical case, a desired noncommutative ``stopping time" argument was discovered to obtain the distribution function inequality form of John-Nirenberg theorem.

Quantitative John--Nirenberg inequality for stochastic processes of bounded mean oscillation

open access: yes, 2022
Stroock and Varadhan in 1997 and Geiss in 2005 independently introduced stochastic processes with bounded mean oscillation (BMO) and established their exponential integrability with some unspecified exponential constant. This result is an analogue of the John--Nirenberg inequality for functions of bounded mean oscillation. In this work, we quantify the

Self-Improving Properties of John–Nirenberg and Poincaré Inequalities on Spaces of Homogeneous Type

open access: yesJournal of Functional Analysis, 1998
The authors consider inequalities of the form \[ \underset{\mu(B)}\bot \int_B| f-f_B| d\mu\leq ca(B)\quad\text{and} \quad \underset{\mu(B)}\bot \int_B | f-f_B| d\mu\leq cb(B,f). \] In either case \(\mu\) is a measure and \(\mu(B)\) denotes the \(\mu\)-measure of \(B\).

A sharp symmetric integral form of the John–Nirenberg inequality

open access: yesProceedings of the American Mathematical Society
We find sharp constants in the symmetric integral form of the John–Nirenberg inequality. The result is based upon the computation of a new interesting Bellman function.
