摘要：
Based on previous experiences with multi-level hierarchical preconditioners (MLHPs) for the solution of finite element equations, the present work extends the ideas to the boundary element technique. Since the system matrix is dense and non-symmetric, the MLHP are implemented within the generalized minimal residual (GMRES) algorithm.
