A Sketched Generalized Krylov Subspace Method for Large-Scale Regularization
Davide Palitta, Mirjeta Pasha
The generalized Krylov subspace (GKS) method is an effective projection technique for large-scale Tikhonov regularization with a general regularization matrix. As the subspace expa…

On the Solution of Large-scale Non-autonomous Differential Riccati Equations: a Numerical Study
Eugenio Mancinelli, Davide Palitta, Jens Saak
We explore the numerical solution of large-scale non-autonomous Differential Riccati Equations (DREs). While we assume to discretize the differential operator using a Backward Diff…

Randomized sketched TT-GMRES for linear systems with tensor structure
Alberto Bucci, Davide Palitta, Leonardo Robol
In the last decade, tensors have shown their potential as valuable tools for various tasks in numerical linear algebra. While most of the research has been focusing on how to compr…
