The author is concerned with sparse preconditioners for densely populated nonsymmetric linear algebraic systems arising from discretizations by boundary element methods. The construction is based on discrete wavelet transforms and makes use of the wavelet compression property and appropriate operator splitting techniques. The suggested wavelet transform results in transformed matrices of band structure.
