Abstract

New results regarding the Sobolev regularity of the principal solution of the linear Beltrami equation ˉf=μf+νf\bar{\partial} f = \mu \partial f + \nu \overline{\partial f} for discontinuous Beltrami coefficients μ\mu and ν\nu are obtained, using Kato-Ponce commutators, obtaining that f\overline \partial f belongs to a Sobolev space with the same smoothness as the coefficients but some loss in the integrability parameter. A conjecture on the cases where the limitations of the method do not work is raised.
