Sequences of matrices with increasing size naturally arise in several contexts and especially
in the discretization of continuous problems, such as integral and differential equations. The …

In computational mathematics, when dealing with a large linear discrete problem (eg, a
linear system) arising from the numerical discretization of a partial differential equation …

In computational mathematics, when dealing with a large linear discrete problem (eg, a
linear system) arising from the numerical discretization of a differential equation (DE), the …

This book describes, in a basic way, the most useful and effective iterative solvers and
appropriate preconditioning techniques for some of the most important classes of large and …

We consider large linear systems of algebraic equations arising from the Finite Element
approximation of coupled partial differential equations. As case study we focus on the linear …

We review and extend the theory of Generalized Locally Toeplitz (GLT) sequences, which
goes back to Tilli's work on Locally Toeplitz sequences and was developed by the second …

The theory of locally Toeplitz (LT) sequences is a powerful apparatus for computing the
asymptotic singular value and eigenvalue distribution of the discretization matrices A_n A n …

Toeplitz matrix reconstruction algorithms (TMRAs) are one of the central subroutines in array
processing for wireless communication applications. The classical TMRAs have shown …

The theory of generalized locally Toeplitz (GLT) sequences is a powerful apparatus for
computing the asymptotic singular value and eigenvalue distribution of matrices A n arising …

We perform a spectral analysis of the preconditioned Hermitian/skew‐Hermitian splitting
(PHSS) method applied to multilevel block Toeplitz linear systems in which the coefficient …
