@Balazs - Are those oscillations in the Feinberg system for all rate constants, or just a very small subset of them?

@Balazs: related to Matthew’s question, Lotka-Volterra has a center for many (all?) parameters. can you detect these cases in your setting?

what method have you used to solve the n-degree polynomial?
Elisenda Feliu

She is not solving the system

i see- thanks.

@Casian: you are right, the Lotka-Volterra gives a center for all rate constants; assuming there are 3 reactions (of which 1 is vertical, 1 is horizontal), we found all centers that are centers for all rate constants, they are straightforward generalizations of the Lotka reactions, this was back in 2017 (https://link.springer.com/article/10.1007/s12346-017-0243-2); in the present paper we looked at nonhorizontal/nonvertical reactions and then I believe center *for all* rate constants is not possible (but I don't have a proof)

@Balasz: Related question: For the systems with the homoclinic orbit surrounding nonlinear centers, are the conditions given (I think it was k3=12k2) sufficient to guarantee a nonlinear center? Or is the relevant set of parameter values even smaller?
