Practical shift choice in the shift-and-invert Krylov subspace evaluations of the matrix exponential
Alexandr Katrutsa, Mike Botchev, Ivan Oseledets
We propose two methods to find a proper shift parameter in the shift-and-invert method for computing matrix exponential matrix-vector products. These methods are useful in the case…

Preconditioning Kaczmarz method by sketching
Alexandr Katrutsa, Ivan Oseledets
We propose a new method for preconditioning Kaczmarz method by sketching. Kaczmarz method is a stochastic method for solving overdetermined linear systems based on a sampling of ma…
