WebIn the present work we extend a local Tb theorem for square functions of Christ [3] and Hofmann [17] to the multilinear setting. We also present a new BM O type interpolation result for square functions associated to multilinear operators. These square function bounds are applied to prove a multilinear local Tb theorem for singular integral ... Webmaximal function, built on these dyadic families. As applications we shall compare the Muckenhoupt classes defined through the d-balls and through this dyadic sets and prove reverse Hölder inequalities for Ap weights on spaces of homogeneous type.

WebWe introduce a dyadic one-sided maximal function M+ D, and prove that it is pointwise equivalent to M+ ; furthermore, since our maximal function is dyadic, Sawyer's original technique [3] can be used to characterize the pairs of weights for which it is bounded (even in the case of different weights).

It is still unknown what the smallest constants Cp,d and Cd are in the above inequalities. However, a result of Elias Stein about spherical maximal functions can be used to show that, for 1 < p < ∞, we can remove the dependence of Cp,d on the dimension, that is, Cp,d = Cp for some constant Cp > 0 only depending on p. It is unknown whether there is a weak bound that is independent of dimension.

WebFor a Euclidean space with a dyadic filtration, the dyadic maximal operator is the above Doob maximal operator. For the dyadic maximal operator, the constant 1 / (p − 1) is the optimal power on [v] A p (see, e.g., [3,4]). It follows that the constant 1 / (p − 1) is also the optimal power on [v] A p for the Doob maximal operator M. read shield band by tara grayce online freeWebMay 22, 2024 · The first sparse domination lemma and a duality argument lead to a result for the dyadic sharp maximal function, which is a variant of the Fefferman–Stein inequality (see [24, Chapter III]).
