Hereditary coreflective subcategories in epireflective subcategories of semitopological groups
The aim of this paper is to study hereditary coreflective subcategories in epireflective subcategories A of the category STopGr of all semitopological groups (and continuous homomorphisms). We describe the hereditary coreflective hu...

Abelian groups: simultaneously reflective and coreflective subcategories versus modules
Abelian groups are characterized that form a reflective and a coreflective subclass (or, that are equivalent to a class of some modules).

Closed hereditary coreflective subcategories in epireflective subcategories of Top
The aim of this paper is to investigate closed hereditary coreflective subcategories in epireflective subcategories A of Top, mainly in the case that ZD ? A ? Tych. Particularly the closed hereditary coreflective hull of the one-poi...

Are all localizing subcategories of a stable homotopy category coreflective?
We prove that, in a triangulated category with combinatorial models, every localizing subcategory is coreflective and every colocalizing subcategory is reflective if a certain large-cardinal axiom (Vopěnka's principle) is assumed true. This ...

Productivity of Coreflective Subcategories of Semitopological Groups
The present paper generalizes to semitopological and quasitopological groups some results achieved by Horst Herrlich and the second author for topological groups. The results concern preserving products in coreflective subcategories. Unlike ...
