    Problems of potential theory and methods of their solution in refined studies on Earth's gravity field

  • Original language description

    The aim of the paper is to show typical problems that are associated with the solution of Poisson?s and Laplace?s equation in gravity field studies based on classical terrestrial as well as modern satellite gravity field data. The use of the method of integral equations and the Green?s function method is approached first. Subsequently the weak solution and variational methods are discussed. The approach is more flexible in general. Some of its fundamental properties are mentioned. In contrast to the classical concept the solution is represented by means of a suitable function basis. This leads to Galerkin?s approximations and a solution of a rather large system of linear equations. Possibilities of using the concept of boundary-value problems in combining the terrestrial and satellite gravity field data are discussed too. As a rule, however, the problems are overdetermined by nature. Therefore, an optimization approach has to be applied together with the methods mentioned above.
