| contents | We study the Dirichlet problem for the complex Monge-Ampère operator with bounded, discontinuous boundary data. If the set of discontinuities is b-pluripolar and the domain is B-regular, we are able to prove existence, uniqueness and some regularity estimates for a large class of complex Monge-Ampère measures. This result is optimal in the unit disk, as boundary functions with b-pluripolar discontinuity then coincides with functions that are continuous almost everywhere. We also show that neither of these properties of the boundary function - being continuous almost everywhere or having discontinuities forming a b-pluripolar set - are necessary conditions in order to establish uniqueness and continuity of the solution in higher dimensions. In particular, there are situations where it is enough to prescribe the boundary behavior at a set of arbitrarily small Lebesgue measure. |
