On galois covering of locally torsionless-finite categories

Let $\mathcal{C}$ be a locally support-finite $k$-category with a $G$-action. It is proved that a Galois covering functor $P: \CC \lrt \CC/G$ induces a Galois covering of categories of their torsionless modules. Using this result, we provide a version of Gabriel's theorem for categories of tors...
