Perfectoid rings as Thom spectra

Abstract

The Hopkins-Mahowald theorem realizes the Eilenberg-Maclane spectra HFpH\mathbb F_p as Thom spectra for all primes pN>0p\in\mathbb N_{>0}. In this article, we record a known proof of a generalization of Hopkins-Mahowald theorem, realizing HkHk as Thom spectra for perfect rings kk, and we provide a further generalization by realizing HRHR as Thom spectra for perfectoid rings RR. We also discuss even further generalizations to prisms (A,I)(A,I) and indicates how to adapt our proofs to Breuil-Kisin case.
