高阶拟范畴与高阶Rezk空间

Higher quasi-categories vs higher Rezk spaces

Dimitri Ara

摘要:

在Joyal的n-cell范畴Θ_n的预层上引入n-拟范畴的概念作为模型范畴结构的映射对象。我们的定义来自于Cisinski和Joyal的一个想法。然而,我们表明,这个想法必须稍微修改,以获得一个合理的概念。本文构造了n-拟范畴的模型范畴与Rezk Θ_n-空间的模型范畴之间的两个Quillen等价,证明了n-拟范畴是(\infty,n)-范畴的模型.当n = 1时,我们恢复了Joyal和Tierney在拟范畴和完备Segal空间之间定义的两个Quillen等价.

英文摘要:

We introduce a notion of n-quasi-categories as fibrant objects of a model category structure on presheaves on Joyal's n-cell category Θ_n. Our definition comes from an idea of Cisinski and Joyal. However, we show that this idea has to be slightly modified to get a reasonable notion. We construct two Quillen equivalences between the model category of n-quasi-categories and the model category of Rezk Θ_n-spaces showing that n-quasi-categories are a model for (\infty, n)-categories. For n = 1, we recover the two Quillen equivalences defined by Joyal and Tierney between quasi-categories and complete Segal spaces.
