On Solvability Of One Boundary Value Problem For Laplace Equation in Banach-Hardy Classes

In this paper we consider the Dirichlet problem for the Laplace equation in Hardy classes generated by an additive-invariant Banach function space on the unit circle.It is shown that the classical Dirichlet problem for the Laplace equation has a unique solution for every boundary function from the considered space.It is considered a boundary problem for the Laplace equation with oblique derivatives in the Hardy classes generated by separable subspaces of rearrangement-invariant spaces in which the infinitely differentiable functions are dense.Noetherness of this problem is established and the index of this problem is calculated.
