The subsequent explanations rest on the weak formulation of the problems. This enables a natural transition to an interpretation of the solution in terms of function bases. However, the need for an integration over the complicated surface of the Earth and an oblique derivative in the boundary condition make the computation of the entries in Galerkin\u2019s matrix extremely demanding. Therefore, an alternative is considered. For constructing Galerkin\u2019s approximations a function basis is generated by the reproducing kernel of the Hilbert space of functions that are harmonic outside an ellipsoid. Obviously, the method of successive approximations is then applied to account for corrections due to the departure of the real boundary from the ellipsoid and due to the obliqueness of the derivative in the boundary condition. The explanations concerning the construction and computation of the reproducing kernel are given more space. Ellipsoidal harmonics, series summation techniques, hypergeometric functions and elliptic integrals come into play as necessary tools. Finally, the convergence of the successive approximations is analyzed and tested."@en . . . . .
