Brauer groups and quotient stacks

D Edidin, B Hassett, A Kresch, A Vistoli - American Journal of …, 2001 - muse.jhu.edu
A natural question is to determine which algebraic stacks are quotient stacks. In this paper
we give some partial answers and relate it to the question of whether, for a scheme X, the …

Twisted sheaves and the period-index problem

M Lieblich - Compositio Mathematica, 2008 - cambridge.org
We use twisted sheaves and their moduli spaces to study the Brauer group of a scheme. In
particular, we (1) show how twisted methods can be efficiently used to re-prove the basic …

Two-primary algebraic 𝐾-theory of rings of integers in number fields

J Rognes, C Weibel, M Kolster - Journal of the American Mathematical …, 2000 - ams.org
We relate the algebraic $ K $-theory of the ring of integers in a number field $ F $ to its étale
cohomology. We also relate it to the zeta-function of $ F $ when $ F $ is totally real and …

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 …

[图书][B] Torus fibrations, gerbes, and duality

R Donagi, T Pantev - 2008 - books.google.com
Let $ X $ be a smooth elliptic fibration over a smooth base $ B $. Under mild assumptions,
the authors establish a Fourier-Mukai equivalence between the derived categories of two …

[图书][B] Brauer groups and the cohomology of graded rings

S Caenepeel - 2020 - books.google.com
This book introduces various notions defined in graded terms extending the notions most
frequently used as basic ingredients in the theory of Azumaya algebras: separability and …

The smooth Whitehead spectrum of a point at odd regular primes

J Rognes - Geometry & Topology, 2003 - msp.org
Let p be an odd regular prime, and assume that the Lichtenbaum–Quillen conjecture holds
for K (ℤ [1∕ p]) at p. Then the p–primary homotopy type of the smooth Whitehead spectrum …
