Parallel multisplitting two-stage iterative methods for large sparse systems of weakly nonlinear equations
Zhong-Zhi Bai,Zhong-Zhi Bai +1 more
TL;DR: A multisplitting two-stage AOR method is presented, which particularly uses the AOR-like iteration as inner iteration and is substantially a relaxed variant of the afore-presented method.
Journal ArticleDOI
On inexact Newton methods based on doubling iteration scheme for non‐symmetric algebraic Riccati equations

Journal ArticleDOI
Optimization of extrapolated Cayley transform with non-Hermitian positive definite matrix ☆
TL;DR: For the extrapolated Cayley transform, the authors gave necessary and sufficient conditions for guaranteeing its convergence and contraction (in the Euclidean norm) and derived upper bounds for the convergence and the contraction factors.
Journal ArticleDOI
On SSOR‐like preconditioners for non‐Hermitian positive definite matrices
TL;DR: Numerical implementations show that Krylov subspace iteration methods such as GMRES, when accelerated by the SSOR‐like preconditioners, are efficient solvers for these classes of non‐Hermitian positive definite linear systems.
Journal ArticleDOI
Product-type skew-Hermitian triangular splitting iteration methods for strongly non-Hermitian positive definite linear systems
TL;DR: Numerical results show that the product-type skew- hermitian triangular splitting iteration method can produce high-quality preconditioners for the Krylov subspace methods for solving large sparse positive definite systems of linear equations of strong skew-Hermitian parts.
