But a good place to look at is Bhatt's notes on perfectoid spaces, especially at Proposition 5.2.5.It explains the main usage of total closures in theory of perfectoid spaces. Nettet9. feb. 2024 · The theorem below generalizes to arbitrary integral ring extensions (under certain conditions) the fact that the ring of integers of a number field is finitely generated over Z ℤ. The proof parallels the proof of the number field result. Theorem 1. Let B B be an integrally closed Noetherian domain with field of fractions K K.
