bireflective subcategory

A bireflective subcategory BCB\subset C is a subcategory which is both reflective and coreflective; i.e. it is a fully faithful functor possesing both left and right adjoints.

Some people use the term in different, weaker meaning, that the unit of the adjunction is a bimorphism.
