This work devises a new smooth representation formula for CZ operators on domains. As a first order consequence of this representation, we obtain a weighted, sharply quantified T(1)-type theorem on Sobolev spaces. Previous results of Prats and Prats-Tolsa are limited to unweighted bounds for convolution-type operators. Our weighted Sobolev inequalities are subsequently applied to obtain quantitative regularity results for solutions to the Beltrami equation with symbol in the critical class W^{k,2}(Omega). All past results, due to Prats among others, based on the Iwaniec scheme are of qualitative nature.

Talk is based on current and ongoing joint work with Green and Wick.
