Product-form stationary distributions for deficiency zero chemical reaction networks.
We consider stochastically modeled chemical reaction systems with mass-action kinetics and prove that a product-form stationary distribution exists for each closed, irreducible subset of the state space if an analogous deterministically modeled system with mass-action kinetics admits a complex balanced equilibrium. Feinberg's deficiency zero theorem then implies that such a distribution exists ...

We consider both deterministically and stochastically modeled chemical reaction systems and prove that a product-form stationary distribution exists for each closed, irreducible subset of the state space of a stochastically modeled system (with quite general kinetics) if the corresponding deterministically modeled system (with mass-action kinetics) admits a complex balanced equilibrium. Feinber...
متن کاملProduct-Form Stationary Distributions for Deficiency Zero Networks with Non-mass Action Kinetics
In many applications, for example when computing statistics of fast subsystems in a multiscale setting, we wish to find 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 mo...
متن کاملProduct-form stationary distributions for deficiency zero networks with non-mass action kinetics: Errata in Example 1
Post-publication a small error was found in Example 1, a typo which also lead to comparing the QSSA and constrained approximations to the wrong distribution. Below we represent this material with the amendments highlighted in red, along with a corrected Figure 1. This didn’t overly affect the presentation of the example, but did underplay the accuracy of the constrained approach for this example.
متن کاملTensor Approximation of Stationary Distributions of Chemical Reaction Networks
We prove that the stationary distribution of a system of reacting species with a weaklyreversible reaction network of zero deficiency in the sense of Feinberg admits tensor-structured approximation of complexity which scales linearly with respect to the number of species and logarithmically in the maximum copy numbers as well as in the desired accuracy. Our results cover the classical mass-acti...
