Krylov Subspace Methods for Quantum Dynamics with Time-Dependent Generators.

Physical Review Letters
Krylov subspace methods in quantum dynamics identify the minimal subspace in which a process unfolds. To date, their use is restricted to time evolutions governed by time-independent generators.

Continuous Analogues of Krylov Subspace Methods for Differential Operators

SIAM Journal on Numerical Analysis, 2019
Analogues of the conjugate gradient method, minimum residual method, and generalized minimum residual method are derived for solving boundary value problems (BVPs) involving ordinary differential e...

Macromodelling oscillators using krylov-subspace methods

Asia and South Pacific Conference on Design Automation, 2006., 2006
We present an efficient method for automatically extracting unified amplitude/phase macromodels of arbitrary oscillators from their SPICE-level circuit descriptions. Such comprehensive oscillator macromodels are necessary for accuracy when speeding up simulation of higher-level circuits/systems, such as PLLs, in which oscillators are embedded. Standard

Error-Minimizing Krylov Subspace Methods

SIAM Journal on Scientific Computing, 1994
This paper first introduces generalized conjugate gradient methods which specialize to error minimizing procedures as well as to residual minimizing methods. General minimum error methods are then introduced, and the two method classes are compared.
