Abstract
We will prove certain general relations in the matrix product ansatz (MPA) for one-dimensional stochastic systems, which are true in both random and s equential updates. We will derive general MPA expressions for the currents and current correlators and find the conditions in the MPA formalism, under which the correlators are site independent or completely vanishing.
