چكيده لاتين :
We study the performance of the backward generalized Gauss-Seidel (BGGS) iterative scheme
to solve stabilized saddle point problems. Moreover, we construct a block triangular preconditioner
from BGGS splitting to improve the rate of convergence of Krylov subspace methods. We
report numerical experiments to illustrate the efficiency of the proposed preconditioner.
