On Kemeny's constant and stochastic complement

Dario Andrea Bini, Fabio Durastante, Sooyeong Kim +1

Given a stochastic matrix $P$ partitioned in four blocks $P_{ij}$ , $i, j = 1, 2$ , Kemeny's constant $κ (P)$ is expressed in terms of Kemeny's constants of the stochastic complements $P_…

Stochastic $p$ th root approximation of a stochastic matrix: A Riemannian optimization approach

Fabio Durastante, Beatrice Meini

We propose two approaches, based on Riemannian optimization, for computing a stochastic approximation of the $p$ th root of a stochastic matrix $A$ . In the first approach, the appro…
