Louise Slade,Harry Levine set U .. and a continuous function f on the boundary U* of U, we understand by the solution of the Dirichlet problem for f a continuous function F on the closure Ū of U which is harmonic in U and coincides with f on U*. A set U is termed . if there exists a solution of the Dirichlet problem, for an
