On higher topological Hochschild homology of rings of integers
Pages: 489 – 507
We determine higher topological Hochschild homology of rings of integers in number fields with coefficients in suitable residue fields. We use the iterative description of higher $THH$ for this and Postnikov arguments that allow us reduce the necessary computations to calculations in homological algebra, starting from the results of Bökstedt and Lindenstrauss–Madsen on (ordinary) topological Hochschild homology.
