摘要: For the solution of a Neumann boundary value problem we consider modified hypersingular integral equation which reflects solvability and scaling conditions non-unique problem. Galerkin discretization elliptic variational describe an efficient element approach is based on fast multipole method for single layer potential. In same way, preconditioner resulting linear system constructed.
