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 GG be a free semigroup generated by finite continuous self-maps acting on compact metric space. We will prove the following results for GG on compact metric spaces. The set of shadowable points of GG is a Borel set. GG has the pseudo-orbit tracing property (POTP) if and only if every point is a shadowable point of GG. The chain recurrent and non-wandering sets of GG coincide when every chain recurrent point is a shadowable point of GG. The space XX is totally disconnected at every shadowable point of GG under certain condition.
