In this paper we consider partial actions of groups on rings, partial skew group rings and partial fixed rings. We study a Morita context associated to these rings, α-partial Galois extensions and related aspects. Finally, we establish conditions to obtain a Morita equivalence between Rα and R⋆αG....
