论每个函子的拉直

On the straightening of every functor

Thomas Blom

AI总结:

本文证明了任意$\infty$-范畴间的函子均可被拉直,通过建立范畴切片与松弛函子范畴的等价关系,并利用Morita范畴的泛性质完成证明。

摘要:

我们证明任意$\infty$-范畴间的函子均可被拉直。更确切地说,对任意$\infty$-范畴$\mathcal{C}$,其上$\infty$-范畴的$\infty$-范畴$(\mathrm{Cat}_{\infty})_{/\mathcal{C}}$与从$\mathcal{C}$到对应关系的双重$\infty$-范畴$\mathrm{Corr}$的单态松弛函子的$\infty$-范畴等价。证明依赖于Morita范畴的某一泛性质,此性质具有独立研究价值。

英文摘要:

We show that any functor between $\infty$-categories can be straightened. More precisely, we show that for any $\infty$-category $\mathcal{C}$, there is an equivalence between the $\infty$-category $(\mathrm{Cat}_{\infty})_{/\mathcal{C}}$ of $\infty$-categories over $\mathcal{C}$ and the $\infty$-category of unital lax functors from $\mathcal{C}$ to the double $\infty$-category $\mathrm{Corr}$ of correspondences. The proof relies on a certain universal property of the Morita category which is of independent interest.
