- Abstract
We consider the solution of linear systems of saddle point problems by two nonlinear iterative methods, which are similar to Uzawa-type methods and called corrected Uzawa methods. Their convergence rates are analyzed. The results of numerical experiments are presented when we apply them to solve the Stokes equations discretized by mixed finite elements. Keywords: Saddle point problem, Uzawa-type algorithm, Schur complement, Stokes equation
