Stability in Chemical Reaction Networks

In this contribution an alternative overview of CRNT (Chemical Reaction Network Theory) concepts is presented. It is oriented to explore the stability properties of chemical reaction networks. In particular emphasis will be placed on the notion of complex balance solutions and its underlying stability.The structure of complex balance solutions will be studied with the help of an analogy with linear mass transport networks. The uniqueness and stability properties of these solutions will be investigated by convex analysis and a Lyapunov function candidate quite connected with chemical potentials.Most methods I make use of in the discussion are familiar, when not standard, to process control what might help devise possible implications (and applications) in the context of robust or decentralized control of process networks. In this concern versions of the zero deficiency theorem adapted to reaction-separation networks might become a promising tool for control design.
