If \(A=\oplus_{g\in G}A_ g\) is a k-algebra (k a field) which is strongly graded over the finite group G, denote by \(A_ e\)-mod (e is the unit element of G) (resp. A-mod) the category of finitely presented \(A_ e\)-modules (resp. A-modules). In this paper, connections between the categories \(A_ e\)-mod and A-mod are studied.
