Abstract

In this paper we introduce a new representation for the multistationarity region of a reaction network, using polynomial superlevel sets. The advantages of using this polynomial superlevel set representation over the formerly existing representations (cylindrical algebraic decompositions, numeric sampling, rectangular division) is discussed, and algorithms to compute this new representation are provided. The results are given for the general mathematical formalism of a parametric system of equations and therefore can be used in other application areas.
