Sampling Error Analysis in Quantum Krylov Subspace Diagonalization [PDF]

open access: yesQuantum
Quantum Krylov subspace diagonalization (QKSD) is an emerging method used in place of quantum phase estimation in the early fault-tolerant era, where limited quantum circuit depth is available. In contrast to the classical Krylov subspace diagonalization

Reduced-Rank Adaptive Filtering Using Krylov Subspace

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A unified view of several recently introduced reduced-rank adaptive filters is presented. As all considered methods use Krylov subspace for rank reduction, the approach taken in this work is inspired from Krylov subspace methods for iterative solutions ...

Extending quasi-GMRES method to solve generalized Sylvester tensor equations via the Einstein product [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
This paper aims to extend a Krylov subspace technique based on an in-complete orthogonalization of Krylov tensors (as a multidimensional exten-sion of the common Krylov vectors) to solve generalized Sylvester tensor equations via the Einstein product ...

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

ILU preconditioning based on the FAPINV algorithm [PDF]

open access: yesOpuscula Mathematica, 2015
A technique for computing an ILU preconditioner based on the factored approximate inverse (FAPINV) algorithm is presented. We show that this algorithm is well-defined for H-matrices.
