In this paper, we consider some preconditioning techniques for a class of block three-by-
three saddle point problems, which arise from a coupled diffuse element-finite element …

In this paper, a class of generalized shift-splitting preconditioners with two shift parameters
are implemented for nonsymmetric saddle point problems with nonsymmetric positive …

For large and sparse saddle point linear systems arising from 2D linearized Navier–Stokes
equations, Benzi and Guo recently studied a dimensional split (DS) preconditioner (Appl …

For the saddle point problem arising from the finite element discretization of the hybrid
formulation of the time-harmonic eddy current problem, we propose an alternating positive …

In this work, we set up a new, general, and computationally efficient way to tackle
parametrized fluid flows modeled through unsteady Navier-Stokes equations defined on …

\noindent We propose and examine block-diagonal preconditioners and variants of
indefinite preconditioners for block two-by-two generalized saddle-point problems. That is …

In this paper, we discuss two classes of parameterized block triangular preconditioners for
the generalized saddle point problems. These preconditioners generalize the common block …

For nonsymmetric saddle point problems, Pan et al.(Appl Math Comput 172: 762–771, 2006)
proposed a deteriorated positive-definite and skew-Hermitian splitting (DPSS) …

We present a preconditioner for saddle point problems. The proposed preconditioner is
extracted from a stationary iterative method which is convergent under a mild condition …

For non-Hermitian saddle point linear systems, Pan, Ng and Bai presented a positive semi-
definite and skew-Hermitian splitting (PSS) preconditioner (Pan et al. Appl. Math. Comput …
