Error Estimates for Arnoldo-Tikhonov Regularization for Ill-Posed Operator Equations
Ronny Ramlau, Lothar Reichel
Most of the literature on the solution of linear ill-posed operator equations, or their discretization, focuses only on the infinite-dimensional setting or only on the solution of…
A spectral method for bipartizing a network and detecting a large anti-community
A. Concas, S. Noschese, L. Reichel +1
Relations between discrete quantities such as people, genes, or streets can be described by networks, which consist of nodes that are connected by edges. Network analysis aims to i…
Eigenvector sensitivity under general and structured perturbations of tridiagonal Toeplitz-type matrices
Silvia Noschese, Lothar Reichel
The sensitivity of eigenvalues of structured matrices under general or structured perturbations of the matrix entries has been thoroughly studied in the literature. Error bounds ar…
Arnoldi decomposition, GMRES, and preconditioning for linear discrete ill-posed problems
Silvia Gazzola, Silvia Noschese, Paolo Novati +1
GMRES is one of the most popular iterative methods for the solution of large linear systems of equations that arise from the discretization of linear well-posed problems, such as D…
