Iterative solution of shifted positive-definite linear systems arising in a numerical method for the heat equation based on Laplace transformation and quadrature [PDF]

open access: yesANZIAM Journal, 2011
AbstractIn earlier work we have studied a method for discretization in time of a parabolic problem, which consists of representing the exact solution as an integral in the complex plane and then applying a quadrature formula to this integral. In application to a spatially semidiscrete finite-element version of the parabolic problem, at each quadrature ...

A comparison of numerical splitting-based methods for Markovian dependability and performability models [PDF]

open access: yes, 1998
Iterative numerical methods are an important ingredient for the solution of continuous time Markov dependability models of fault-tolerant systems. In this paper we make a numerical comparison of several splitting-based iterative methods. We consider the

Preconditioned fully implicit PDE solvers for monument conservation [PDF]

open access: yes, 2010
Mathematical models for the description, in a quantitative way, of the damages induced on the monuments by the action of specific pollutants are often systems of nonlinear, possibly degenerate, parabolic equations. Although some the asymptotic properties

A convergence analysis of SOR iterative methods for linear systems with weak H-matrices

open access: yesOpen Mathematics, 2016
It is well known that SOR iterative methods are convergent for linear systems, whose coefficient matrices are strictly or irreducibly diagonally dominant matrices and strong H-matrices (whose comparison matrices are nonsingular M-matrices).

Two Iterative Methods for Solving Linear Interval Systems

open access: yesApplied Computational Intelligence and Soft Computing, 2018
Conjugate gradient is an iterative method that solves a linear system Ax=b, where A is a positive definite matrix. We present this new iterative method for solving linear interval systems Ãx̃=b̃, where à is a diagonally dominant interval matrix, as ...

On parallel multisplitting block iterative methods for linear systems arising in the numerical solution of Euler equations

open access: yesJournal of Computational and Applied Mathematics, 2015
The paper studies the convergence of some parallel multisplitting block iterative methods for the solution of linear systems arising in the numerical solution of Euler equations. Some sufficient conditions for convergence are proposed. As special cases the convergence of the parallel block generalized AOR (BGAOR), the parallel block AOR (BAOR), the ...
