Palindromic linearization and numerical solution of nonsymmetric algebraic T-Riccati equations

Peter Benner, Bruno Iannazzo, Beatrice Meini +1

We identify a relationship between the solutions of a nonsymmetric algebraic T-Riccati equation (T-NARE) and the deflating subspaces of a palindromic matrix pencil, obtained by arr…

Geometric means of quasi-Toeplitz matrices

Dario A. Bini, Bruno Iannazzo, Jie Meng

We study means of geometric type of quasi-Toeplitz matrices, that are semi-infinite matrices of the form , where represents a compact o…

Geometries on the cone of positive-definite matrices derived from the power potential and their relation to the power means

Nadia Chouaieb, Bruno Iannazzo, Maher Moakher

We study a Riemannian metric on the cone of symmetric positive-definite matrices obtained from the Hessian of the power potential function . We give explicit expre…
