Sharp inequalities for dyadic A 1 weights
Sharp inequalities for dyadic A 1 weights
We show how the Bellman function method can be used to obtain sharp inequalities for the maximal operator of a dyadic A 1 weight on $${\mathbb{R}^n}$$ . Using this approach, we determine the optimal constants in the corresponding weak-type estimates. Furthermore, we provide an alternative, simpler proof of the related …
