The Picard group in equivariant homotopy theory via stable module categories
Achim Krause
We develop a mechanism of "isotropy separation for compact objects" that explicitly describes an invertible -spectrum through its collection of geometric fixed points and gluing…

Witt vectors with coefficients and characteristic polynomials over non-commutative rings
Emanuele Dotto, Achim Krause, Thomas Nikolaus +1
For a not-necessarily commutative ring R we define an abelian group W(R;M) of Witt vectors with coefficients in an R-bimodule M. These groups generalize the usual big Witt vectors…

Bökstedt periodicity and quotients of DVRs
Achim Krause, Thomas Nikolaus
In this note we compute the topological Hochschild homology of quotients of DVRs. Along the way we give a short argument for Bökstedt periodicity and generalizations over various o…
