Prisms and prismatic cohomology

B Bhatt, P Scholze - Annals of Mathematics, 2022 - projecteuclid.org
We introduce the notion of a prism, which may be regarded as a" deperfection" of the notion
of a perfectoid ring. Using prisms, we attach a ringed site---the prismatic site---to a p-adic …

[HTML][HTML] Nilpotence and descent in equivariant stable homotopy theory

A Mathew, N Naumann, J Noel - Advances in Mathematics, 2017 - Elsevier
Let G be a finite group and let F be a family of subgroups of G. We introduce a class of G-
equivariant spectra that we call F-nilpotent. This definition fits into the general theory of …

Mapping stacks and categorical notions of properness

D Halpern-Leistner, A Preygel - Compositio Mathematica, 2023 - cambridge.org
One fundamental consequence of a scheme-descent results which hold in the setting of
derived algebraic geometry but not in classical algebraic geometry. Our main applications …

A -Adic 6-Functor Formalism in Rigid-Analytic Geometry

L Mann - arXiv preprint arXiv:2206.02022, 2022 - arxiv.org
We develop a full 6-functor formalism for $ p $-torsion\'etale sheaves in rigid-analytic
geometry. More concretely, we use the recently developed condensed mathematics by …

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 …

The Picard group of topological modular forms via descent theory

A Mathew, V Stojanoska - Geometry & Topology, 2016 - msp.org
This paper starts with an exposition of descent-theoretic techniques in the study of Picard
groups of E∞–ring spectra, which naturally lead to the study of Picard spectra. We then …

K-theoretic obstructions to bounded t-structures

B Antieau, D Gepner, J Heller - Inventiones mathematicae, 2019 - Springer
Schlichting conjectured that the negative K-groups of small abelian categories vanish and
proved this for noetherian abelian categories and for all abelian categories in degree-1-1 …

Cosupport in tensor triangular geometry

T Barthel, N Castellana, D Heard, B Sanders - arXiv preprint arXiv …, 2023 - arxiv.org
We develop a theory of cosupport and costratification in tensor triangular geometry. We
study the geometric relationship between support and cosupport, provide a conceptual …

Descent in algebraic -theory and a conjecture of Ausoni–Rognes

D Clausen, A Mathew, N Naumann, J Noel - Journal of the European …, 2020 - ems.press
Let A→ B be a G-Galois extension of rings, or more generally of E∞-ring spectra in the
sense of Rognes. A basic question in algebraic K-theory asks how close the map K (A)→ K …

The chromatic fourier transform

T Barthel, S Carmeli, TM Schlank… - Forum of Mathematics …, 2024 - cambridge.org
We develop a general theory of higher semiadditive Fourier transforms that includes both
the classical discrete Fourier transform for finite abelian groups at height-modules [-12pc] …
