Partial actions of groups on quivers and path algebras

In this article, we introduce the concept of partial actions of a group $G$ on quivers and demonstrate that for any given partial action of G on a quiver $\mathrm{\Gamma }$, there exists another quiver, ${\mathrm{\Gamma }}^{\mathrm{\prime }}$ with a full $G$-action. This is an enveloping action of the partial action of $G$ on $\mathrm{\Gamma }$. We also introduce partial actions of groups on algebras by subalgebras instead of ideals and we define enveloping actions in this case. We show that any partial action of a group on a path algebra that is induced by a partial action on a quiver has an enveloping action.
