Chemical Organizations: Theory and Applications

Tomas Veloz (University of British Columbia)

Abstract:

Chemical Organization Theory (COT) studies the dynamical properties of reaction networks avoiding the computationally expensive analysis of their corresponding systems of ODE or stochastic simulations. Instead, COT focuses on how the occurrence of a reaction affects the availability of molecules in the network to perform other reactions and studies the conditions under which a system can self-maintain. It has been proved that some special sub-networks, so called organizations, are the only possible sub-networks that correspond to asymptotically stable solutions of the system of differential equations that governs the dynamics of the system. This has important consequences from both dynamical and computational points of view. This talk would cover the basic aspects of the theory and two novel applications based on reaction networks as a paradigm to study social systems will be presented.
