Some symmetric monoidal categories have a notion of duality without being a *-autonomous category. However, they can be a weak -autonomous category.
A weak -autonomous category is a symmetric closed monoidal category with an object such that the canonical morphism
which is the transpose of the evaluation map
is a monomorphism for all . (Here, denotes the internal hom.)
A -autonomous category is a weak -autonomous category such that for every object , is an isomorphism.
A strictly weak -autonomous category is a weak -autonomous category such that for at least one object , is not an isomorphism. Equivalently, a strictly weak -autonomous category is a weak -autonomous category which is not a -autonomous category.
