A parameterized block LU preconditioning for double saddle point problems
Hamed Aslani, Mehdi Najafi Kalyani, Davod Khojasteh Salkuyeh
We present a biparametric preconditioning technique for large, sparse, non-symmetric, and non-singular double saddle point problems. The preconditioner is induced using a stationar…
A variant of the block preconditioner for indefinite complex symmetric linear systems
Mehdi Makhdomi, Davod Khojasteh Salkuyeh
In this paper, we propose an efficient preconditioner for solving indefinite complex symmetric linear systems within a block preconditioning framework. We analyze the convergence o…
A block preconditioner with two parameters for double saddle point systems in liquid crystal director modeling
Mehdi Makhdomi, Davod Khojasteh Salkuyeh, Morad Ahmadnasab
This paper introduces a novel block preconditioner for a class of double saddle point systems arising from the finite element discretization of liquid crystal director modeling. We…
Inexact versions of several block-splitting preconditioners for indefinite least squares problems
Mohaddese Kaveh Shaldehi, Davod Khojasteh Salkuyeh
This paper introduces inexact versions of several block-splitting preconditioners for solving the three-by-three block linear systems arising from a special class of indefinite lea…
