چکیده مقاله |
In this paper, we analyse the semi-convergence of the improved symmetric successive over-relaxation method for singular saddle point problems. In fact, when the $(1,2)$-th block of the coefficient matrix is rank deficient, the saddle point problem is singular. Here, we study sufficient conditions for semi-convergence of the improved symmetric successive over-relaxation method, that satisfy in suitable restrictions. |
