Parameter region for multistationarity in $n-$site phosphorylation networks

no code implementations17 Jun 2022 Elisenda Feliu, Nidhi Kaihnsa, Timo de Wolff, Oğuzhan Yürük

For any $n$, we provide sufficient conditions for the polynomial to be positive and hence, preclude multistationarity, and also sufficient conditions for it to attain negative values and hence, enable multistationarity.
