Two-Grid Methods for Hermitian positive definite linear systems connected with an order relation
S Serra-Capizzano, C Tablino-Possio - Calcolo, 2014 - Springer
Given a multigrid procedure for linear systems with coefficient matrices A_n, we discuss the
optimality of a related multigrid procedure with the same smoother and the same projector …
