Shadowable points of free semigroup actions
Abstract
The shadowable points of dynamical systems has been well-studied by Morales \cite{MR3535492}. This paper aims to generalize the main results obtained by Morales to free semigroup actions. To this end, we introduce the notion of shadowable points of a free semigroup action. Let be a free semigroup generated by finite continuous self-maps acting on compact metric space. We will prove the following results for on compact metric spaces. The set of shadowable points of is a Borel set. has the pseudo-orbit tracing property (POTP) if and only if every point is a shadowable point of . The chain recurrent and non-wandering sets of coincide when every chain recurrent point is a shadowable point of . The space is totally disconnected at every shadowable point of under certain condition.
