text: In category theory, a branch of mathematics, a subcategory A of a category B is said to be isomorphism closed or replete if every B -isomorphism h : A → B with A ∈ A belongs to A . This implies that both B and h − 1 : B → A belong to A as well. A subcategory that is isomorphism closed and full is called strictly full. In the case of full subcategories it is sufficient to check that every B -object that is isomorphic to an A -object is also an A -object. This condition is very natural. For exampl
