Abstract

Sharp tangential Lipschitz estimates for the inhomogeneous Cauchy Riemann equations with Lp data on strongly pseudoconvex doma ins in complex manifolds are proved. Estimates in both isotropic and non-isotropic spaces of functions of bounded mean oscillation are proved.

Tangential estimates for a large class of domains are shown to follow from those on the ball.

In the course of the proofs a fractional integration theorem of independent interest is proved.
