Thermodynamic Limits of Stochastic Chemical Reaction Networks with Phosphorylation

Lucie Laurence, Philippe Robert

In this paper we investigate the stability properties of a fundamental mechanism of biological cells called phosphorylation. The system is a chemical reaction network (CRN) for whi…

Scaling Methods for Stochastic Chemical Reaction Networks

Lucie Laurence, Philippe Robert

The asymptotic properties of some Markov processes associated to stochastic chemical reaction networks (CRNs) driven by the kinetics of the law of mass action are analyzed. The sca…

Noise-induced stabilization in a chemical reaction network without boundary effects

Andrea Agazzi, Lucie Laurence

We present a chemical reaction network that is unstable under deterministic mass action kinetics, exhibiting finite-time blow-up of trajectories in the interior of the state space,…

Analysis of Stochastic Chemical Reaction Networks with a Hierarchy of Timescales

Lucie Laurence, Philippe Robert

We investigate a class of stochastic chemical reaction networks with chemical species , \ldots, , and whose complexes are only of the form , ,\ld…

Stochastic Chemical Reaction Networks with Discontinuous Limits and AIMD processes

Lucie Laurence, Philippe Robert

In this paper we study a class of stochastic chemical reaction networks (CRNs) for which chemical species are created by a sequence of chain reactions. We prove that under some con…
