Convergence behavior of generalized parameterized Uzawa method for singular saddle-point problems

Abstract

In this paper, we will seek the least squares solution for singular saddle-point problems. The parameterized Uzawa (PU) method is further studied and a generalized PU (GPU) proper splitting is proposed. The convergence behavior of the corresponding GPU iteration is studied. It is proved that the GPU iteration method can converge to the best least squares… (More)
