Abstract
This paper discusses convergence behavior of the nonlinear inexact Uzawa al gorithm for solving saddle-point problems presented in a recent paper of Br amble, Pasciak, and Vassilev (SIAM J. Numer. Anal., 34 (1997), pp. 1072-109 2). It is shown that this algorithm converges under a condition weaker than that stated in their paper.
