Circulant preconditioners with unbounded inverses
Linear Algebra and its Applications, 1995 Let \(A_ n = [a_{i-j}]\) be a Hermitian Toeplitz matrix whose entries are the Fourier coefficients of a function \(f\). The quality of a preconditioner \(M_ n\) is measured by how well the singular values of \(M_ n^{-1} A_ n\) cluster at 1. This clustering has been proved for \(M_ n = C_ n\) and \(M_ n = S_ n\) (the optimal and the simplified circulant

Multipreconditioned GMRES for simulating stochastic automata networks
Open Mathematics, 2018 Stochastic Automata Networks (SANs) have a large amount of applications in modelling queueing systems and communication systems. To find the steady state probability distribution of the SANs, it often needs to solve linear systems which involve their ...

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

On the construction of preconditioners by subspace decomposition
Journal of Computational and Applied Mathematics, 1990 AbstractA preconditioner for the iterative solution of symmetric linear systems which arise in Galerkin's method is obtained by decomposition of the space into orthogonal subspaces. The preconditioner corresponds to a particular bilinear form and is actually a 2-level multigrid method.
