Multi-grid methods are the most efficient tools for solving elliptic
boundary value problems. The reader finds here an elementary
introduction to multi-grid algorithms as well as a comprehensive
convergence analysis. One section describes special applications
(convection-diffusion equations, singular perturbation problems,
eigenvalue problems, etc.). The book also contains a complete
presentation of the multi-grid method of the second kind, which has
important applications to integral equations (e.g. the "panel method")
and to numerous other problems. Readers with a practical interest in
multi-grid methods will benefit from this book as well as readers with a
more theoretical interest.
