摘要

我们证明了四种不同的定义笛卡尔振动和笛卡尔模型结构的方法都是Quillen等效的:1。在标记简单集上(由于Lurie[31])， 2。2 .关于双斜空间(由于deBrito [12])，在二项式集上，4。在标记的简单空间上。证明这些等价的主要方法是利用Joyal-Tierney定义的拟范畴与完全Segal空间之间的Quillen等价以及Lurie的拉直构造。

Quasi-categories vs. Segal spaces: Cartesian edition

We prove that four different ways of defining Cartesian fibrations and the Cartesian model structure are all Quillen equivalent:

1.
On marked simplicial sets (due to Lurie [31]),
2.
On bisimplicial spaces (due to deBrito [12]),
3.
On bisimplicial sets,
4.
On marked simplicial spaces.

The main way to prove these equivalences is by using the Quillen equivalences between quasi-categories and complete Segal spaces as defined by Joyal–Tierney and the straightening construction due to Lurie.
