Product-form stationary distributions for deciency zero networks with non-mass action kinetics

Abstract

In many applications, for example when computing statistics of fast subsystems in a multiscale setting, we wish to nd the stationary distributions of systems of continuous time Markov chains. Here we present a class of models that appears naturally in certain averaging approaches whose stationary distributions can be computed explicitly. In particular, we study continuous time Markov chain models for biochemical interaction systems with non-mass action kinetics whose network satises a certain constraint. Analogous with previous related results, the distributions can be written in product form.
