The topological period-index conjecture

Benjamin Antieau, Ben Williams

We prove the topological analogue of the period-index conjecture in each dimension away from a small set of primes.

On the Beilinson fiber square

Benjamin Antieau, Akhil Mathew, Matthew Morrow +1

Using topological cyclic homology, we give a refinement of Beilinson's -adic Goodwillie isomorphism between relative continuous -theory and cyclic homology. As a result, we g…

Valuation rings are derived splinters

Benjamin Antieau, Rankeya Datta

We give three proofs that valuation rings are derived splinters: a geometric proof using the absolute integral closure, a homological proof which reduces the problem to checking th…
