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 $\omega$-limit set $\omega (z)$ that contains no equilibrium points is a closed orbit.
