Multilevel Projection Methods for Partial Differential EquationsMultilevel Projection Methods for Partial Differential Equations

Stephen F. McCormick



CBMS-NSF Regional Conference Series in Applied Mathematics 62

The multilevel projection method is a new formalism that provides a framework for the development of multilevel algorithms in a very general setting. This methodology guides the choices of all the major multilevel processes, including relaxation and coarsening, and it applies directly to global or locally-refined discretizations.

This book was developed from lectures at the CBMS-NSF Regional Conference on Multigrid and Multilevel Adaptive Methods for Partial Differential Equations in June 1991, and is a supplement to Multilevel Adaptive Methods for Partial Differential Equations, also written by Stephen F. McCormick.
