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.
