Abstract

Multilevel algorithms have been used to generate fast algorithms for Fourier transforms and inversion of matrices in finite element method. These algorithms could invert an integral operator in less than O (N3) operations and expedite a matrix-vector multiply to require O(N log N) or O(N) operations. A multilevel algorithm for expediting matrix vector multiply in an iterative solution of boundary integral equation is described. This algorithm has O(N(log N)2) complexity, and for a large problem, O(N log N) complexity.
