Abstract :
Boundary integral equations for bodies of revolution have a Green´s function kernel that can be written as the azimuthal integral over the free-space Green´s function. We show that existing approximation methods for computing this integral suffer from efficiency or stability problems. Improvement of one of these methods leads to controllable accuracy while retaining efficiency.
