我们引入单范畴su-范畴,它是单范畴上的单输入高阶过程的抽象范畴概念。该定义将低阶过程的基础范畴C与洞或超映射的单范畴V分离,并公理化了部分应用于二分过程所需的相容性。对于固定的单范畴基础C,单范畴su-范畴、单范畴su-函子和单范畴su-自然变换构成2-范畴MonSuCatC。我们随后证明,余端光学的范畴Optic[C]在该2-范畴中是2-初始的,为余端光学提供了一种替代的泛性质刻画,将其视为单洞上下文的最小单范畴理论。
英文摘要
We introduce monoidal su-categories, an abstract categorical notion of single-input higher-order process over a monoidal category. The definition separates a base category C of lower-order processes from a monoidal category V of holes or supermaps and axiomatizes the compatibility needed for partial application to bipartite processes. For a fixed monoidal base C, monoidal su-categories, monoidal su-functors, and monoidal su-natural transformations form a 2-category MonSuCatC. We then show that the category Optic[C] of coend optics is 2-initial in this 2-category, giving an alternative universal-property characterisation of coend optics as the minimal monoidal theory of single-hole contexts.
