The -topology

B Bhatt, A Mathew - Duke Mathematical Journal, 2021 - projecteuclid.org
We study a Grothendieck topology on schemes which we call the arc-topology. This
topology is a refinement of the v-topology (the pro-version of Voevodsky'sh-topology), where …

Extending torsors on the punctured Spec(Ainf)

J Anschütz - Journal für die reine und angewandte Mathematik …, 2022 - degruyter.com
We prove that torsors under parahoric group schemes on the punctured spectrum of
Fontaine's ring A inf, extend to the whole spectrum. Using descent we can extend a similar …

Almost coherent modules and almost coherent sheaves

B Zavyalov - arXiv preprint arXiv:2110.10773, 2021 - arxiv.org
We review the theory of almost coherent modules that was introduced in" Almost Ring
Theory" by Gabber and Ramero. Then we globalize it by developing a new theory of almost …

A 6-functor formalism for solid quasi-coherent sheaves on the Fargues-Fontaine curve

J Anschütz, ACL Bras, L Mann - arXiv preprint arXiv:2412.20968, 2024 - arxiv.org
We develop a 6-functor formalism $\mathcal {D} _ {[0,\infty)}(-) $ with $\mathbb {Z} _p $-
linear coefficients on small v-stacks, and discuss consequences for duality and finiteness for …

Logarithmic adic spaces: some foundational results

H Diao, KW Lan, R Liu, X Zhu - Simons Symposium on P-adic Hodge …, 2019 - Springer
We develop a theory of log adic spaces by combining the theories of adic spaces and log
schemes, and study the Kummer étale and pro-Kummer étale topology for such spaces. We …

The six functors for Zariski-constructible sheaves in rigid geometry

B Bhatt, D Hansen - Compositio Mathematica, 2022 - cambridge.org
We prove a generic smoothness result in rigid analytic geometry over a characteristic zero
non-archimedean field. The proof relies on a novel notion of generic points in rigid analytic …

Rigid-Analytic Artin-Grothendieck Vanishing

O Gabber, B Zavyalov - arXiv preprint arXiv:2402.08741, 2024 - arxiv.org
In this paper, we address two conjectures about the rigid-analytical analogues of the Artin--
Grothendieck Vanishing Theorem. First, we show the remaining cases of the Artin …

Extending torsors on the punctured Spec (A_inf)

J Anschütz - arXiv preprint arXiv:1804.06356, 2018 - arxiv.org
We prove that torsors under parahoric group schemes on the punctured spectrum of
Fontaine's ring $ A_ {\mathrm {inf}} $, extend to the whole spectrum. Using descent we can …

Perfectoidness via Sen Theory and Applications to Shimura Varieties

T He - arXiv preprint arXiv:2407.14488, 2024 - arxiv.org
Sen's theorem on the ramification of a $ p $-adic analytic Galois extension of $ p $-adic local
fields shows that its perfectoidness is equivalent to the non-vanishing of its arithmetic Sen …

Geometric arcs and fundamental groups of rigid spaces

P Achinger, M Lara, A Youcis - Journal für die reine und angewandte …, 2023 - degruyter.com
We develop the notion of a geometric covering of a rigid space 𝑋, which yields a larger class
of covering spaces than that studied previously by de Jong. Geometric coverings are closed …
