We prove two basic structural properties of the algebraic K-theory of rings after K(1)-localization at an implicit prime p. Our first result (also recently obtained by Land–Meier–Tamme by different methods) states that \(L_{K(1)} K(R)\) is insensitive to inverting p on R; we deduce this from recent advances in prismatic cohomology and \(\mathrm {TC}\). Our second result yields a Künneth formula in K(1)-local K-theory for adding p-power roots of unity to R.

关于K(1)-局部K-理论的评论

我们证明了在隐式素数pK(1)定位后环的代数K理论的两个基本结构性质。我们的第一个结果(最近也由Land–Meier–Tamme通过不同方法获得)指出\(L_ {K(1)} K(R)\)R上的p反转不敏感;我们从棱镜同调和\(\ mathrm {TC} \)的最新进展中推断出这一点。我们的第二结果产生在Künneth式ķ(1) -本地ķ -理论用于添加p -power统一到的根- [R
