A note on the generalization of parameterized inexact Uzawa method for singular saddle point problems

Recently, Zhang and Wang studied the generalized parameterized inexact Uzawa methods (GPIU) for solving singular saddle point problems (Zhang and Wang, 2013 [22]). In this note, we continue to discuss the semi-convergence of GPIU for solving singular saddle point problems, and weaken some semi-convergent conditions.
