本文针对素数p和特征p的完美仿射域K,构造了带C_p作用的几何正规次完美仿射拓扑空间,其v环空间范畴的商非仿射,表明仿射完美空间的有限商稳定性不适用于次完美空间。
AI 中文摘要
对每个素数p和每个特征p的完美仿射域K,我们构造一个具有C_p作用的几何正规次完美仿射拓扑空间,其在v环空间范畴中的商不是仿射的。该源是稳定一致且层化的,而在不动点处的共尾有理邻域序列获得了新的一阶不变截面,这些截面无法通过完备有理局部化下降。因此,仿射完美空间的有限商稳定性不能推广到次完美空间。
英文摘要
For every prime $p$ and every perfectoid field $K$ of characteristic $p$, we construct a geometrically normal sousperfectoid affinoid adic space with a $C_p$-action whose quotient in the category of $v$-ringed spaces is not adic. The source is stably uniform and sheafy, while a cofinal sequence of rational neighborhoods at a fixed point acquires new degree-one invariant sections that do not descend by completed rational localization. Consequently, finite quotient stability for affinoid perfectoid spaces does not extend to sousperfectoid spaces.
