Let be a finite dimensional algebra. Let be a functorially finite exact subcategory of -mod with enough projective and injective objects and be its monomorphism category. It turns out that the category has almost split sequences. We show an explicit formula for the Auslander-Reiten translation in . Furthermore, if is a stably -Calabi-Yau Frobenius category, we calculate objects under powers of Auslander-Reiten translation in the triangulated category .
