Noise-reducing cascadic multilevel methods for linear discrete ill-posed problems
Cascadic multilevel methods for the solution of linear discrete ill-posed problems with noise-reducing restriction and prolongation operators recently have been developed for the r...

The convergence of the cascadic conjugate-gradient method applied to elliptic problems in domains with re-entrant corners
Abstract. We study the convergence properties of the cascadic conjugategradient method (CCG-method), which can be considered as a multilevel method without coarse-grid correction. ...
