An algebraic approach to biochemical reaction networks

Under the law of mass-action, the concentrations of the species of a chemical reaction network are often modelled by means of a system of polynomial ordinary differential equations. The polynomial structure of the system allows us to use techniques that come from algebra and graph theory to study properties of the system, mainly at steady state. This is the basis of the so-called Chemical Reaction Network Theory. In this talk I will start by presenting the formalism of the approach and discuss the questions we would like to address. I will proceed to present some of the results we have recently obtained, mainly focusing on the number of steady states of the system.
