Abstract

We enlarge the area of applicability of the Bellman function method to estimates in the spirit of the John--Nirenberg inequality abandoning certain convexity assumptions. As an application, we consider a characteristic of a function that is much smaller than the BMO\mathrm{BMO} norm, but whose finiteness leads to the exponential integrability of the function.
