Abstrakt: We consider the Dirichlet problem for the Laplace operator with rational data on the boundary of a planar domain. Our main results include a characterization of the disk as the only domain for which all solutions are rational, and a characterization of the simply connected quadrature domains as the only ones for which all solutions are algebraic of a certain type. This note is an exposition, and full details will appear in a forthcoming paper. [ABSTRACT FROM AUTHOR]
