:''We propose a new non-linear multigrid that is a kind of exact approximation scheme. To solve non-linear problems, we add the current approximation vector as a column of the prolongator. This construction guarantees that the current approximation is present in the coarse-space. Thus, in the limit, the coarse-space contains the exact solution. We apply our method to the generalized eigenvalue problem and show very promising numerical results. We discuss shortly the issue of convergence theory that is currently in progress. | :''We propose a new non-linear multigrid that is a kind of exact approximation scheme.
