In this paper, we provide semi-convergence results of the parameterized inexact Uzawa method with singular preconditioners for solving singular saddle point problems. We also provide numerical experiments to examine the effectiveness of the parameterized inexact Uzawa method with singular preconditioners.
Keywords: singular saddle point problem, iterative method, Uzawa method, semi-convergence, Moore-Penrose inverse
