Perfectoid towers generated from prisms

Commutative Algebra 2026-02-25 v3 Number Theory

Abstract

We present a unified construction of perfectoid towers from specific prisms which covers all the previous constructions of (p-torsion-free) perfectoid towers. By virtue of the construction, perfectoid towers can be systematically constructed for a large class of rings with Frobenius lift. Especially, any Frobenius lifting of a reduced Fp\mathbb{F}_p-algebra has a perfectoid tower.
