课程内容简介:
Multigrid methods can provide very efficient iterative methods for the
solution of large systems of (non)linear algebraic equations, resulting
for instance from the discretization of partial differential equations.
In a multigrid method several coarsened approximations of the algebraic
system and well-designed smoothers are used to accelerate the
convergence of the iterative method. This can result in very efficient
iterative methods, but if one wants to develop new multigrid algorithms
or understand the performance of existing algorithms, then multilevel
analysis is indispensible.

In this class an outline of basic multigrid and iterative methods will
be given and mathematical techniques to understand and predict their
performance will be discussed. No prior knowledge of multigrid or
iterative methods will be required.

After this class you should be able to use basic iterative and multigrid
methods, analyze and (approximately) predict multigrid performance using
multilevel analysis and apply these techniques to improve and test
multigrid algorithms. The main applications will be from numerical
discretizations of partial differential equations.
