Cartesian分解系统与Grothendieck纤维化

Cartesian Factorization Systems and Grothendieck Fibrations

David Jaz Myers

摘要:

每一个Grothendieck纤维化都在其定义域上产生一个垂直/直角正交分解系统。我们定义了一个正交分解系统,其中左类满足2-of-3,并且在右类的拉回下是封闭的。我们努力表明,这一定义抽象的垂直/carnival分解系统的Grothendieck纤维化的关键特征,并给出各种2类分解系统和Grothendieck纤维化之间的比较,以证明这种关系。然后,我们给出了一个结构,对应于纤维的Grothendieck纤维化的水平上的carbohydorfactorization系统。除了最后的双分类结果,本文是完全回顾以前建立的材料。它应被视为一个临时说明。

英文摘要:

Every Grothendieck fibration gives rise to a vertical/cartesian orthogonal factorization system on its domain. We define a cartesian factorization system to be an orthogonal factorization in which the left class satisfies 2-of-3 and is closed under pullback along the right class. We endeavor to show that this definition abstracts crucial features of the vertical/cartesian factorization system associated to a Grothendieck fibration, and give comparisons between various 2-categories of factorization systems and Grothendieck fibrations to demonstrate this relationship. We then give a construction which corresponds to the fiberwise opposite of a Grothendieck fibration on the level of cartesian factorization systems. Apart from the final double categorical results, this paper is entirely review of previously established material. It should be read as an expository note.
