We consider an arbitrary Abelian category A and a subcategory T closed under extensions
and direct summands, and characterize those T that are (semi-) special preenveloping in A; …

We consider an arbitrary Abelian category $\mathcal {A} $ and a subcategory $\mathcal {T}
$ closed under extensions and direct summands, and characterize those $\mathcal {T} $ that …

In this talk we revisit the problem of determining when a torsion class in an arbitrary Abelian
category is a (pre) enveloping class. In this sense, we extend the bijection, classically given …

We extend to the context of Abelian categories the bijection, classically given in categories
of modules, between equivalence classes of tilting (resp., finendo quasi-tilting) modules and …
