摘要：

The present paper is concerned with the application of iterative techniques to solve boundary element method (BEM) systems of equations. Initially, a brief description of some algorithms which have been employed for symmetric positive-definite matrices is given (finite element method matrices, for instance). Subsequently, non-symmetric versions of these algorithms are described and their performance is checked for BEM matrices, through various numerical experiments. Preconditioned algorithms were found to work quite well.
