Abstract
We investigate the structure of \(\omega \)-limit (resp. \(\alpha \)-limit) sets for a monotone map f on a regular curve X. We show that for any \(x\in X\) (resp. for any negative orbit \((x_{n})_{n\ge 0}\) of x), the \(\omega \)-limit set \(\omega _{f}(x)\) (resp. \(\alpha \)-limit set \(\alpha _{f}((x_{n})_{n\ge 0})\)) is a minimal set. This also holds for \(\alpha \)-limit set \(\alpha _{f}(x)\) whenever x is not a periodic point. These results extend those of Naghmouchi [24] established whenever f is a homeomorphism on a regular curve and those of Abdelli [1], whenever f is a monotone map on a local dendrite. Further results related to the basin of attraction of an infinite minimal set are also obtained.
