Block structures, g.a.c.s. approximation, and distributions

Year: 2025

Type: article

Abstract: In the present note, we consider the problem of identifying the singular value and eigenvalue distribution in the Weyl sense of block matrix-sequences with rectangular Toeplitz blocks. Using recent results regarding the notion of generalized approximating class of sequences, we arrive to prove general results, which suggest practical preconditioning strategies for dealing with the fast solution of related large linear systems.
