On multilevel iterative methods for integral equations of the second kind and related problems
We describe a unifying framework for multigrid methods and projection- iterative methods for integral equations of the second kind, and for the iterative aggregation method for solving input-output relations. The methods are formulated as successive approximations combined with a defect correction in a subspace. Convergence proofs use contraction arguments and thus involve the nonlinear case automatically. Some new results are presented.
