Riassunto

This book is an introduction and analysis of the multigrid approach for the numerical solution of large sparse linear systems arising from the discretization of elliptic partial differential equations. It gives special attention to the powerful matrix-based-multigrid approach, which is particularly useful for problems with variable coefficients and nonsymmetric and indefinite problems. The approach used here applies not only to model problems on rectangular grids but also to more realistic applications with complicated grids and domains and discontinuous coefficients. The discussion draws connections between multigrid and other iterative methods such as domain decomposition. The theoretical background provides insight about the nature of multigrid algorithms and how and why they work. The theory is written in simple algebraic terms, and therefore, requires preliminary knowledge only in basic linear algebra and calculus.

Recensione

From the reviews:

"This book contains a wealth of information about using multilevel methods to solve partial differential equations (PDEs) ... . A common matrix-based framework for developing these methods is used throughout the book. This approach allows methods to be developed for problems under three very different conditions ... . This book will be insightful for practitioners in the field. ... students will enjoy studying this book to see how the many puzzle pieces of the multigrid landscape fit together." (Loyce Adams, SIAM Review, Vol. 47 (3), 2005)

"The discussion very often includes important applications in physics, engineering and computer science. The style is clear, the details can be understood without any serious prerequisite. The usage of multigrid method for unstructured grids is exhibited by a well commented C++ program. This way the book is suitable for anyone ... who needs numerical solution of partial differential equations." (Peter Hajnal, Acta Scientiarum Mathematicarum, Vol. 70, 2004)
