每个在小量子 Q 上丰富的类别之间的分配器都会在逆变和协变预滑类别之间产生两个附属物,从而产生两个单子。这两个附加项分别是范畴论中Isbell附加项和Kan扩展的推广。证明了这两个过程是函子的,信息态射在分布者之间起到态射的作用; Q 类别的自由补全函子通过这两个函子进行分解。
Each distributor between categories enriched over a small quantaloid Q gives rise to two adjunctions between the categories of contravariant and covariant presheaves, and hence to two monads. These two adjunctions are respectively general- izations of Isbell adjunctions and Kan extensions in category theory. It is proved that these two processes are functorial with infomorphisms playing as morphisms between distributors; and that the free cocompletion functor of Q-categories factors through both of these functors.
