A defect-correction algorithm for quadratic matrix equations, with applications to quasi-Toeplitz matrices

Dario Bini, Beatrice Meini

A defect correction formula for quadratic matrix equations of the kind $A_{1} X^{2} + A_{0} X + A_{- 1} = 0$ is presented. This formula, expressed by means of an invariant subspace of a suitable…

Relaxed Fixed Point Iterations for Matrix Equations Arising in Markov Chains Modeling

Luca Gemignani, Beatrice Meini

We present some accelerated variants of fixed point iterations for computing the minimal non-negative solution of the unilateral matrix equation associated with an M/G/1-type Marko…

Computing eigenvalues of semi-infinite quasi-Toeplitz matrices

D. A. Bini, B. Iannazzo, B. Meini +2

A quasi-Toeplitz (QT) matrix is a semi-infinite matrix of the form $A = T (a) + E$ where $T (a)$ is the Toeplitz matrix with entries $(T (a))_{i, j} = a_{j - i}$ , for $a_{j - i} \in C$ , $i…

An edge centrality measure based on the Kemeny constant

D. Altafini, D. A. Bini, V. Cutini +2

A new measure $c (e)$ of the centrality of an edge $e$ in an undirected graph $G$ is introduced. It is based on the variation of the Kemeny constant of the graph after removing the…
