Abstract

We develop a method for proving sup-norm and Hölder estimates for ∂ on wide class of finite type pseudoconvex domains in ℂn. A fundamental obstruction to proving sup-norm estimates is the possibility of singular complex curves with exceptionally high order of contact with the boundary. Our method handles this problem, and in ℂ3, we prove sup-norm and Hölder estimates for all bounded, pseudoconvex domains with real-analytic boundary.
