A note on GPIU method for generalized saddle point problems

摘要

In this note, the generalized parameterized inexact Uzawa method, abbreviated as the GPIU method, for solving the generalized saddle point problems with symmetric positive semi-definite (2, 2) block is studied. The convergence of the method is established, which is an extension of the results obtained in a recent paper by Zhou and Zhang (2009) [22].
