We introduce a certain class of so-called perfectoid rings and spaces, which give a natural framework for Faltings’ almost purity theorem, and for which there is a natural tilting operation which exchanges characteristic 0 and characteristic p. We deduce the weight-monodromy conjecture in certain cases by reduction to equal characteristic. 
Perfectoid spaces and the homological conjectures
This is a survey of recent advances in commutative algebra, especially in mixed characteristic, obtained by using the theory of perfectoid spaces. An explanation of these techniques and a shortExpand
Another proof of the almost purity theorem for perfectoid valuation rings
The almost purity theorem is central to the geometry of perfectoid spaces and has numerous applications in algebra and geometry. This result is known to have several different proofs in the case thatExpand
Abstract We give proofs of de Rham comparison isomorphisms for rigid-analytic varieties, with coefficients and in families. This relies on the theory of perfectoid spaces. Another new ingredient isExpand
Perfectoid Shimura varieties of abelian type
We prove that Shimura varieties of abelian type with infinite level at $p$ are perfectoid. As a corollary, the moduli spaces of polarized K3 surfaces with infinite level at $p$ are also perfectoid.
Logarithmic adic spaces: some foundational results
We develop a theory of log adic spaces by combining the theories of adic spaces and log schemes, and study the Kummer \'etale and pro-Kummer \'etale topology for such spaces. We also establish theExpand
On the Witt Vectors of Perfect Rings in Positive Characteristic
The purpose of this article is to prove some results on the Witt vectors of perfect F p -algebras. Let A be a perfect F p -algebra for a prime integer p, and assume that A has the property P. ThenExpand
Perfectoid spaces and the weight-monodromy conjecture, after Peter Scholze
The monodromy weight conjecture is one of the main remaining open problems on Galois representations. It implies that the local Galois action on the ℓ-adic cohomology of a proper smooth variety isExpand
$p$-adic vanishing cycles as Frobenius-fixed points
Given a smooth formal scheme over the ring of integers of a mixed-characteristic perfectoid field, we study its $p$-adic vanishing cycles via de Rham--Witt and $q$-de Rham complexes.
Note on weight-monodromy conjecture for p-adically uniformized varieties
We prove the weight-monodromy conjecture for varieties which are p-adically uniformized by a product of the Drinfeld upper half spaces. It is an easy consequence of Dat's work on the cohomologyExpand
Some recent advances in topological Hochschild homology
We give an account of the construction of the Bhatt–Morrow–Scholze motivic filtration on topological cyclic homology and related invariants, focusing on the case of equal characteristic p and theExpand


Galois representations arising from some compact Shimura varieties
Our aim is to establish some new cases of the global Langlands correspondence for GLm. Along the way we obtain a new result on the description of the cohomology of some compact Shimura varieties. LetExpand

Monodromy weight filtration is independent of l
In this paper, we prove the l-independence of monodromy weight filtration for a geometrically smooth variety over an equicharacteristic local field. We also prove the l-independence for the geometricExpand
Weight-monodromy conjecture for p-adically uniformized varieties
The aim of this paper is to prove the weight-monodromy conjecture (Deligne’s conjecture on the purity of monodromy filtration) for varieties p-adically uniformized by the Drinfeld upper half spacesExpand
