The smallest bimolecular mass action reaction networks admitting Andronov–Hopf bifurcation

M Banaji, B Boros - Nonlinearity, 2023 - iopscience.iop.org
We address the question of which small, bimolecular, mass action chemical reaction
networks (CRNs) are capable of Andronov–Hopf bifurcation (from here on abbreviated …

Oscillations in three‐reaction quadratic mass‐action systems

M Banaji, B Boros, J Hofbauer - Studies in Applied …, 2024 - Wiley Online Library
It is known that rank‐two bimolecular mass‐action systems do not admit limit cycles. With a
view to understanding which small mass‐action systems admit oscillation, in this paper we …

The inheritance of local bifurcations in mass action networks

M Banaji, B Boros, J Hofbauer - arXiv preprint arXiv:2312.12897, 2023 - arxiv.org
We consider local bifurcations of equilibria in dynamical systems arising from chemical
reaction networks with mass action kinetics. In particular, given any mass action network …

Planar chemical reaction systems with algebraic and non-algebraic limit cycles

G Craciun, R Erban - arXiv preprint arXiv:2406.05057, 2024 - arxiv.org
The Hilbert number $ H (n) $ is defined as the maximum number of limit cycles of a planar
autonomous system of ordinary differential equations (ODEs) with right-hand sides …
