摘要

我们给出了一个交换环的 $p$-typical 维特向量环的构造的普遍性质,赋予了维特向量弗罗贝尼乌斯和弗尔希本,并将这一构造推广到派生环境。我们定义了一个$p$-典型派生$\delta$-卡蒂埃环的$\infty$-类别,并证明派生环的$p$-典型维特向量的派生环自然不是这个$\infty$-类别中的对象。此外,我们还证明,对于任意prime $p$,$p$-典型维特向量的派生环的形成给出了所有派生环的$infty$-类别与由$V$-完整对象组成的所有派生$p$-典型$\delta$-卡蒂埃环的全子类之间的等价性。

Witt vectors and $δ$-Cartier rings
We give a universal property of the construction of the ring of $p$-typical Witt vectors of a commutative ring, endowed with Witt vectors Frobenius and Verschiebung, and generalize this construction to the derived setting. We define an $\infty$-category of $p$-typical derived $\delta$-Cartier rings and show that the derived ring of $p$-typical Witt vectors of a derived ring is naturally an object in this $\infty$-category. Moreover, we show that for any prime $p$, the formation of the derived ring of $p$-typical Witt vectors gives an equivalence between the $\infty$-category of all derived rings and the full subcategory of all derived $p$-typical $\delta$-Cartier rings consisting of $V$-complete objects.
