A fast direct solver for boundary integral equations in two dimensions
The authors are concerned with important linear algebra issues associated with the discretization of boundary integral equations involving non-oscillatory kernels. They elaborate a fast numerical technique in order to provide directly a compressed (``data-sparse'') factorization of the inverse of a large matrix which comes with the discretization process. The compression algorithm is carefully analyzed and several examples are carried out in order to underline the efficiency of the technique.
