摘要:

In this paper it is proved that if T:A→Xis a topological functor satisfying certain conditions, then there is a Galois Connection between the class of bireflective subcategories ofAand the class of epireflective subcategories ofAthat are not bireflective and that are contained in the subcategory of separated objects ofA. In general such a correspondence is not bijective.
