Convergence of iterative methods for stabilized saddle-point problems

Abstract

The convergence of two classes of iterative methods for stabilized saddle-point problems (inexact Uzawa algorithms and a class of methods with symmetric preconditioners) are studied using Zulerhner’s unified approach.

Keywords:

• Indefinite systems
• Preconditioners
• Saddle-point problems
• Stabilization
• Uzawa algorithms
