Building on the embedding of an n-abelian category into an abelian category as an n-cluster-tilting subcategory of , in this paper, we relate the n-torsion classes of with the torsion classes of . Indeed, we show that every n-torsion class in is given by the intersection of a torsion class in with . Moreover, we show that every chain of n-torsion classes in the n-abelian category induces a Harder–Narasimhan filtration for every object of . We use the relation between and to show that every Harder–Narasimhan filtration induced by a chain of n-torsion classes in can be induced by a chain of torsion classes in . Furthermore, we show that n-torsion classes are preserved by Galois covering functors, thus we provide a way to systematically construct new (chains of) n-torsion classes.
