On the convergence of iterative methods for stabilized saddle point problems |
|
| Abstract: | The convergence of the inexact Uzawa method for stabilized saddle point problems was analysed in a recent paper by Cao, Evans and Qin. We show that this method converges under conditions weaker than those stated in their paper. |
