摘要：
The algebraic properties of the matrix arising for the three-dimensional Dirichlet problem for Lame equations in a rotational domain by the boundary element method are considered. The use of the special basis leads to a matrix having a block structure with sparse blocks. The possible strategies for the efficient solution of the above problem are discussed.
