Disconnectivity in Multistationarity Regions of Cascade of Goldbeter--Koshland Loops
Nidhi Kaihnsa, Kaizhang Wang
Dynamics of reaction networks is often modelled by parameterised polynomials and describing the set of parameters for which the system attains multiple positive equilibrium states…
Algebraic Distance Optimization in Polyhedral Norms
Eliana Duarte, Nidhi Kaihnsa, Julia Lindberg +2
We consider the distance minimization problem to a real algebraic variety $X \subseteq \RR^n$ when the metric is induced by a polyhedral norm. Each point in the variety has a Voron…
Connectivity of Parameter Regions of Multistationarity for Multisite Phosphorylation Networks
Nidhi Kaihnsa, Máté L. Telek
The parameter region of multistationarity of a reaction network contains all the parameters for which the associated dynamical system exhibits multiple steady states. Describing th…
Network reduction and absence of Hopf Bifurcations in dual phosphorylation networks with three Intermediates
Elisenda Feliu, Nidhi Kaihnsa
Phosphorylation networks, representing the mechanisms by which proteins are phosphorylated at one or multiple sites, are ubiquitous in cell signalling and display rich dynamics suc…
