Solving Coupled Cluster Equations by the Newton Krylov Method
Frontiers in Chemistry, 2020 We describe using the Newton Krylov method to solve the coupled cluster equation. The method uses a Krylov iterative method to compute the Newton correction to the approximate coupled cluster amplitude.

Krylov Subspace Acceleration of Waveform Relaxation
SIAM Journal on Numerical Analysis, 2003 In recent years, certain very old ideas of iterative algorithms traditionally used to linear algebraic problems, come back with the changed name of waveform relaxation when applied in a changed context, for example to problems of ordinary differential equations (ODEs) or partial differential equations (PDEs).
