Adaptive Uzawa algorithm for nonsymmetric generalized saddle point problem
Hailun Shen, Hua Xiang
In this paper, we extend the inexact Uzawa algorithm in [Q. Hu, J. Zou, SIAM J. Matrix Anal., 23(2001), pp. 317-338] to the nonsymmetric generalized saddle point problem. The techn…

An Inexact Uzawa Algorithm for Generalized Saddle-Point Problems and Its Convergence
Kazufumi Ito, Hua Xiang, Jun Zou
We propose an inexact Uzawa algorithm with two variable relaxation parameters for solving the generalized saddle-point system. The saddle-point problems can be found in a wide clas…

Perturbation Analysis and Randomized Algorithms for Large-Scale Total Least Squares Problems
Pengpeng Xie, Yimin Wei, Hua Xiang
In this paper, we present perturbation analysis and randomized algorithms for the total least squares (TLS) problems. We derive the perturbation bound and check its sharpness by nu…
