C_2-fixed points of topological Hochschild homology of the integers at two, by John Rognes

We prove by computation that the C_2-fixed points and the C_2-homotopy fixed points of the topological Hochschild homology of the integers are homotopy equivalent, after two-adic completion and passing to connective covers. Hence the same holds for the C_{2^n}-fixed points by a theorem of Tsalidis.
