Multistability

A chemical reaction network $\mathcal{N} = (\mathcal{S},\mathcal{C},\mathcal{R})$ endowed with some kinetic scheme is said to exhibit multistability or multistationarity if there exist multiple positive chemical concentration vectors $\vec{c}_1, \ldots, \vec{c}_p \in \mathbb{R}_{>0}^m$ such that $\Gamma \vec{R}(t,\vec{c}_i) = 0$.

Multistability is an important topic in the application of chemical reaction network theory because it is believed to be the phenomenon underlying many biochemical switches.
