Abstract

ABSTRACT
The Nyström method for solving integral equations on polygonal regions reduces to the
solution of a finite system of linear equations. The size of this system can easily very large,
prohibitively so for solution by direct methods, and this necessitates the use of iterative
methods. In this paper two-grid iterative method is applied for fast solution of these large
systems.
