In the context of (bio)chemical reaction networks, the dynamics of the concentrations of the chemical species over time are often modelled by a system of parameter-dependent ordinary differential equations, which are typically polynomial or described by rational functions. The polynomial structure of the system allows the use of techniques from algebra to study properties of the system around steady states, for arbitrary parameter values. In this talk I will introduce the formalism of the theory of reaction networks, highlight questions that can be addressed using tools from applied algebra, and discuss a network reduction approach based on elimination of intermediates.
