Comparison Theorems for Splittings of M-matrices in (block) Hessenberg Form
Luca Gemignani, Federico Poloni
Some variants of the (block) Gauss--Seidel iteration for the solution of linear systems with -matrices in (block) Hessenberg form are discussed. Comparison results for the asymp…

Orthogonal iterations on Structured Pencils
Roberto Bevilacqua, Gianna M. Del Corso, Luca Gemignani
We present a class of fast subspace tracking algorithms based on orthogonal iterations for structured matrices/pencils that can be represented as small rank perturbations of unitar…
