Jianlei Li, Ting‐Zhu Huang, Liang Li · The ANZIAM Journal · 2010
Abstract Inexact Uzawa algorithms for solving nonlinear saddle-point problems are proposed. A simple sufficient condition for the convergence of the inexact Uzawa algorithms is obtained. Numerical experiments show that the inexact Uzawa algorithms are convergent.
