Dynamics of a class of time-period strongly 2-cooperative system: integer-valued Lyapunov function and embedding property of limit sets

Mengmeng Gao, Dun Zhou

We construct an integer-valued Lyapunov function $\sigma (\cdot )$ for generalized negative cyclic feedback system; and prove that $\sigma (\cdot )$ on any $\omega$-limit set which generated by Poinc…
