Two-grid methods for nonlinear multi-dimensional weakly singular integral equations
A two-grid iteration method for nonlinear multi-dimensional weakly singular integral equations is considered. The main result is a theorem about the convergence and the convergence rate of the studied method. The author proves for the nonlinear equation the same rate of convergence as for the linear equation. Moreover, the presented method is illustrated by an example.
