Generic Poincaré-Bendixson Theorem for singularly perturbed monotone systems with respect to cones of rank-$2$

Abstract

We investigate the singularly perturbed monotone systems with respect to cones of rank $2$ and obtain the so called Generic Poincaré-Bendixson theorem for such perturbed systems, that is, for a bounded positively invariant set, there exists an open and dense subset $\mathcal{P}$ such that for each $z\in \mathcal{P}$, the $\ddot{I}‰$-limit set $\ddot{I}‰(z)$ that contains no equilibrium points is a closed orbit.
