A note on sharp weighted bound for Haar shift and multiplier
Abstract
We provide elementary proofs for the terms that are left in the work of Kelly Bickel, Sandra Pott, Maria C. Reguera, Eric T. Sawyer, Brett D. Wick who proved the sharp weighted A2 bound for Haar shifts and Haar multiplier. Our proofs use weighted square function estimate, Carleson embedding and Wilson's system.
