Sharp reverse Hölder property for A∞ weights on spaces of homogeneous type
(Elsevier, 2012-12-15)In this article we present a new proof of a sharp Reverse Hölder Inequality for A∞ weights. Then we derive two applications: ...

Sharp weighted estimates for dyadic shifts and the A2 conjecture
(De Gruyter, 2014-02)We give a self-contained proof of the A2 conjecture, which claims that the norm of any Calderón–Zygmund operator is bounded ...
