Multigrid-based preconditioning for saddle-point problems.

Benson, Thomas.


  • Abstract: Saddle-point problems arise in a variety of applications, from finance to physics, including liquid crystals research, solid mechanics, and fluid dynamics. These linear systems are often challenging to solve due to their indefiniteness, and many common preconditioners yield poor performance or fail altogether, unless closely tailored to the application. Multigrid methods are, however, kn... read more
