Some algorithms for maximum volume and cross approximation of symmetric semidefinite matrices

Stefano Massei

Finding the $r \times r$ submatrix of maximum volume of a matrix $A \in R^{n \times n}$ is an NP hard problem that arises in a variety of applications. We propose a new greedy…

Compress-and-restart block Krylov subspace methods for Sylvester matrix equations

Daniel Kressner, Kathryn Lund, Stefano Massei +1

Block Krylov subspace methods (KSMs) comprise building blocks in many state-of-the-art solvers for large-scale matrix equations as they arise, e.g., from the discretization of part…
