研究内部范畴作用的单子方法,构造相关单子并刻画为广义作用单子,还证明其能产生良好的广义下降概念。
AI 中文摘要
我们开发了一种关于内部范畴作用的单子方法。给定一个内部范畴,我们在一个切片上构造一个单子,其代数是该内部范畴的作用。然后,我们对以这种方式产生的单子给出了完整的刻画,称之为广义作用单子。最后,我们证明这些单子产生了一个表现良好的广义下降概念。
英文摘要
We develop a monadic approach to actions of internal categories. Given an internal category, we construct a monad on a slice whose algebras are the actions of that internal category. Then, we give a complete characterization of the monads that arise in this way; we call them generalized action monads. Finally, we prove that these monads yield a well-behaved notion of generalized descent.
