In general, a -category  is an -category, or, alternatively, an - and  -category  with certain additional conditions for the canonical morphism from direct sums to products of any family of objects in  [1]).

A -category is defined as a category that has products, coproducts and a zero object, and if the morphism is a monomorphism for any family of objects in (p. 81 in [2]).

One readily obtains the result that a -category is ([2]).
