作为lax函子的Morita context

Morita contexts as lax functors

Stephen Lack

摘要:

众所周知,单子等价于终端范畴之外的lax函子。森田上下文在这里被证明是松散函子的混沌范畴与两个对象。这使得森田上下文理论中的各个方面都可以被看作是关于松弛函子的一般结果的特例。我们对此给出的解释可以作为那些熟悉单子理论的人对lax函子的介绍。我们还证明了一些非常一般的结果沿这些线路相对于一个给定的2-comonad,与经典的情况下,普通单子理论的情况下的身份comonad猫。

英文摘要:

Monads are well known to be equivalent to lax functors out of the terminal category. Morita contexts are here shown to be lax functors out of the chaotic category with two objects. This allows various aspects in the theory of Morita contexts to be seen as special cases of general results about lax functors. The account we give of this could serve as an introduction to lax functors for those familiar with the theory of monads. We also prove some very general results along these lines relative to a given 2-comonad, with the classical case of ordinary monad theory amounting to the case of the identity comonad on Cat.
