摘要

我们证明了从小置换范畴到\(\mathcal {G}_*\) -范畴、\(\mathcal {G}_*\) -简单集合和连接谱的三个k理论多函子中的每一个都是同伦理论的等价。对于每一个k理论多函子，我们描述了一个显式同伦逆函子。作为我们关于点图范畴的一般结果的单独应用，我们观察到Bohmann-Osorno \(\mathcal {E}_*\) -范畴的右诱导同伦理论等价于点简单范畴的同伦理论。

Multifunctorial K-theory is an equivalence of homotopy theories

We show that each of the three K-theory multifunctors from small permutative categories to \(\mathcal {G}_*\)-categories, \(\mathcal {G}_*\)-simplicial sets, and connective spectra, is an equivalence of homotopy theories. For each of these K-theory multifunctors, we describe an explicit homotopy inverse functor. As a separate application of our general results about pointed diagram categories, we observe that the right-induced homotopy theory of Bohmann–Osorno \(\mathcal {E}_*\)-categories is equivalent to the homotopy theory of pointed simplicial categories.
