Abstract

We study the natural resolution of the conjugated Haar multiplier Mw12TσMw12,M_{w^{\frac{1}{2}}}T_{\sigma}M_{w^{-\frac{1}{2}}}, where the multiplication operators Mw±12M_{w^{\pm\frac{1}{2}}} are decomposed into their canonical paraproduct decompositions. We prove that each constituent operator obtained from this resolution has a linear bound on L2(Rd;w)L^2(\mathbb{R}^d;w) in terms of the A2A_{2} characteristic of ww. The main tools used are a product formula for Haar coefficients, the Carleson Embedding Theorem, the linear bound for the square function, and the well-known linear bound of TσT_{\sigma} on L2(Rd,w).L^2(\mathbb{R}^d,w).
