Period Rings with Big Coefficients and Applications I

TL;DR

This paper explores extending the theory of period rings with big coefficients to more general adic spaces, aiming to develop a broader framework for p-adic Hodge structures and their applications in noncommutative geometry and representation theory.

Contribution

It introduces a generalization of period rings with big coefficients to a wider class of adic spaces, inspired by recent advances in p-adic Hodge theory and noncommutative geometry.

Findings

Extension of period rings to general adic spaces

Connections to Drinfeld's lemma for diamonds

Motivations from noncommutative Tamagawa number conjectures

Abstract

Following ideas of Kedlaya-Liu, we are going to consider extending our previous work to the context of more general adic spaces, which will be corresponding deformation of the relative $p$-adic Hodge structure over more general adic spaces. This means that the deformation could be also realized by an adic spaces (perfectoid, preperfectoid, relatively perfectoid and so on). Parts of the whole project here actually are inspired by the corresponding Drinfeld's lemma for diamonds after Scholze, as well as the work from Carter-Kedlaya-Z\'abr\'adi which is aimed at studying the representation theory of products of \'etale fundamental groups. Moreover, we gain motivations from noncommutative analytic geometries and noncommutative Tamagawa number conjectures.
