Large deviations and the matrix product ansatz
Davide Gabrielli, Federica Iacovissi
We consider probability measures on , the set of sequences of symbols on a finite alphabet of length , that give a weight to each sequence in terms of a collection of m…

Mixtures, Markov bridges and the matrix product ansatz
Davide Gabrielli, Federica Iacovissi
We give a probabilistic characterization of the set of measures that can be represented by the matrix product ansatz. By suitably enlarging the state space, we show that a probabil…
