Iterative Solution Methods and Preconditioners for Block-Tridiagonal Systems of Equations

SIAM Journal on Matrix Analysis and Applications, 1992
The authors study semicirculant preconditioners \(M\) used in CG-like iterative methods for solving linear systems \(Bu=b\) of \(n\) algebraic equations arising typically from the implicit time and finite difference spatial discretizations of initial-boundary value problems for linear systems of partial differential equations of the form \(\partial u ...

Efficient Preconditioner and Iterative Method for Large Complex Symmetric Linear Algebraic Systems

East Asian Journal on Applied Mathematics, 2017
AbstractWe discuss an efficient preconditioner and iterative numerical method to solve large complex linear algebraic systems of the form (W + iT)u = c, where W and T are symmetric matrices, and at least one of them is nonsingular. When the real part W is dominantly stronger or weaker than the imaginary part T, we propose a block multiplicative (BM ...

Performance of Neumann Expansion Preconditioners for Iterative Methods with Geotechnical Elastoplastic Applications

International Journal of Geomechanics, 2016
AbstractBecause most geotechnical analyses may involve elastoplastic geomaterials, a robust solution scheme is of critical importance to the efficiency of the entire finite-element (FE) computation. To accelerate the Krylov subspace iterative methods, some preconditioning techniques have been developed based on the factorization of elastic stiffness ...

Iterative Method with the Preconditioner (I + S_max) for H‐Matrices

PAMM, 2003
AbstractIn 2002 Kotakemori et al. have reported the Modified Gauss‐Seidel method with a preconditioner (I + Smax). The convergence of the new method they investigated only for Z‐matrices, for which the new method can be superior to other iterative methods. But, in the case of H‐matrices this method can be superior to the others, too.
