On the application of Liao’s method for solving linear systems

open access: yesAin Shams Engineering Journal, 2013
In this paper, an analytical attitude is proposed for solving linear systems by Homotopy Analysis Method (HAM). On the basis of HAM we design new iterative methods. The convergence properties of the proposed method have been analyzed.

New SOR-like methods for solving the Sylvester equation

open access: yesOpen Mathematics, 2014
We present new iterative methods for solving the Sylvester equation belonging to the class of SOR-like methods, based on the SOR (Successive Over-Relaxation) method for solving linear systems.

Numerical Simulation of One-Phase Flow to Multi-Stage Hydraulically Fractured Horizontal Well [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2016
This paper presents a method of numerical simulation of one-phase flow near multi-stage fractured horizontal well in oil reservoir. Differential models for flows within reservoir and within fractures are formulated separately on the basis of Darcy's law.

A preconditioned AOR iterative scheme for systems of linear equations with L-matrics

open access: yesOpen Mathematics, 2019
In this paper we investigate theoretically and numerically the new preconditioned method to accelerate over-relaxation (AOR) and succesive over-relaxation (SOR) schemes, which are used to the large sparse linear systems.

Preconditioned Low-rank Riemannian Optimization for Linear Systems with Tensor Product Structure [PDF]

open access: yesSIAM Journal on Scientific Computing, 2015
The numerical solution of partial differential equations on high-dimensional domains gives rise to computationally challenging linear systems. When using standard discretization techniques, the size of the linear system grows exponentially with the ...

Convergence on Gauss-Seidel iterative methods for linear systems with general H-matrices

open access: yes, 2014
It is well known that as a famous type of iterative methods in numerical linear algebra, Gauss-Seidel iterative methods are convergent for linear systems with strictly or irreducibly diagonally dominant matrices, invertible $H-$matrices (generalized ...

A Modified SSOR Preconditioning Strategy for Helmholtz Equations

open access: yesJournal of Applied Mathematics, 2012
The finite difference method discretization of Helmholtz equations usually leads to the large spare linear systems. Since the coefficient matrix is frequently indefinite, it is difficult to solve iteratively.

One-Parameter Controlled Non-Dissipative Unconditionally Stable Explicit Structure-Dependent Integration Methods with No Overshoot

open access: yesApplied Sciences, 2021
Although many families of integration methods have been successfully developed with desired numerical properties, such as second order accuracy, unconditional stability and numerical dissipation, they are generally implicit methods.

Probabilistic Linear Solvers: A Unifying View

open access: yes, 2018
Several recent works have developed a new, probabilistic interpretation for numerical algorithms solving linear systems in which the solution is inferred in a Bayesian framework, either directly or by inferring the unknown action of the matrix inverse ...

Towards Time-Limited $\mathcal H_2$-Optimal Model Order Reduction [PDF]

open access: yes, 2017
In order to solve partial differential equations numerically and accurately, a high order spatial discretization is usually needed. Model order reduction (MOR) techniques are often used to reduce the order of spatially-discretized systems and hence ...
