Abstract
We show that for 1 < p < ∞, weight w ∈ A p , and any L 2-bounded Calderón-Zygmund operator T, there is a constant C T,p such that the weak- and strong-type inequalities
hold, where T ♮ denotes the maximal truncations of T and \({\left\| w \right\|_{{A_p}}}\) denotes the Muckenhoupt A p characteristic of w. These estimates are not improvable in the power of \({\left\| w \right\|_{{A_p}}}\). Our argument follows the outlines of those of Lacey-Petermichl-Reguera (Math. Ann. 2010) and Hytönen-Pérez-Treil-Volberg (arXiv, 2010) and contains new ingredients, including a weak-type estimate for certain duals of T ♮ and sufficient conditions for two-weight inequalities in L p for T ♮. Our proof does not rely upon extrapolation.
